Hydrocephalus Preventions - The Phytochemicals

Hydrocephalus, also known as "water in the brain" is defined as complex and multifactorial neurological disorders of accumulation of cerebrospinal fluid (CSF) in the cavity of brain of that can lead to intracranial pressure inside the side, resulting of brain trauma, stroke, infection, tumor, etc.
Preventions
Other than structures abnormalities caused by genetic defects, accidence, etc., most acquired hydrocephalus can be prevented by enhancing the immune system in fighting against forming of free radicals causes of irregular cells growth and foreign invasion such virus and bacteria and reduce the risk of diseases cause of Hydrocephalus, such as dementia.
Phytochemicals to prevent Hydrocephalus
C.1. Rosemarinol, is a phytochemical monophenols, found in essential oil of labiate herbs like Rosemary and also in variety of other plants.
1. Chemical stabilization of fish oil
In the study of fish oil undergoes multiple changes in its physical properties and its autoxidation occurred found that rosemary extract rich in carnosic acid to ternary blends of tocopherols, ascorbyl palmitate and lecithin or Citrem significantly retarded autoxidation, according to "Chemical stabilization of oils rich in long-chain polyunsaturated fatty acids during storage" by Pop F.

2. Anti-inflammatory effects
In the research of the extract of rosemary leaves from supercritical fluid extraction and its anti inflammatory effects found that the yield of 3.92% and total phenolics of 213.5 mg/g extract obtained from the most effective extraction conditions showed a high inhibitory effect on lipid peroxidation (IC(50) 33.4 μg/mL). Both the SC-CO(2) extract and CA markedly suppressed the LPS-induced production of nitric oxide (NO) and tumor necrosis factor-α (TNF-α), as well as the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), phosphorylated inhibitor-kappaB (P-IκB), and nuclear factor-kappaB (NF-κB)/p65 in a dose-dependent manner, according to the study of "Anti-inflammatory effects of supercritical carbon dioxide extract and its isolated carnosic acid from Rosmarinus officinalis leaves" by Kuo CF, Su JD, Chiu CH, Peng CC, Chang CH, Sung TY, Huang SH, Lee WC, Chyau CC.(51)

3. Supercritical fluid
In the investigation of rosemary extract could enhance antioxidant defenses and improve antioxidant status in aged rats found that rosemary extract produced a decrease in antioxidant enzyme activity, lipid peroxidation and ROS levels that was significant for catalase activity in heart and brain, NOS in heart, and LPO and ROS levels in different brain tissues. These observations suggest that the rosemary supplement improved the oxidative stress status in old rats, according to "Protective effect of supercritical fluid rosemary extract, Rosmarinus officinalis, on antioxidants of major organs of aged rats" by Posadas SJ, Caz V, Largo C, De la Gándara B, Matallanas B, Reglero G, De Miguel E.(52)

C.2. Gingerole
Gingerole, is also known as gingerol, a phytochemical of Flavonoids (polyphenols) found in fresh ginger. and in variety of other plants. The herb has been used to treat nausea and vomiting of pregnancy, motion sickness, rheumatoid arthritis, relieve migraine, etc.
1. Antioxidant and anti-inflammatory effects
In the investigation of the effectiveness of chemical constituents of Zingiber officinale Rosc. (Zingiberaceae)in treating oxidative stress found that compounds [6]-gingerol, [8]-gingerol, [10]-gingerol and [6]-shogaol of the herb scavenges of 1,1-diphenyl-2-picyrlhydrazyl (DPPH), superoxide and hydroxyl radicals, inhibitsof N-formyl-methionyl-leucyl-phenylalanine (f-MLP) induced reactive oxygen species (ROS) production in human polymorphonuclear neutrophils (PMN), lipopolysaccharide induced nitrite and prostaglandin E(2) production in RAW 264.7 cells, according to the study of "Comparative antioxidant and anti-inflammatory effects of [6]-gingerol, [8]-gingerol, [10]-gingerol and [6]-shogaol" by Dugasani S, Pichika MR, Nadarajah VD, Balijepalli MK, Tandra S, Korlakunta JN(53)

2. Dementia
In the study of Ginger effectiveness in treating dementia in South Asia with A 70% aqueous/methanolic extract of dried ginger (Zo.Cr) was used. Zo.Cr tested positive for the presence of terpenoids, flavonoids, secondary amines, phenols, alkaloids and saponins found that
specific inhibition of butyrylcholinesterase (BuChE) rather than acetylcholinesterase enzyme. Different pure compounds of ginger also showed spasmolytic activity in stomach fundus, with 6-gingerol being the most potent. 6-Gingerol also showed a specific anti-BuChE effect, according to "Muscarinic, Ca(++) antagonist and specific butyrylcholinesterase inhibitory activity of dried ginger extract might explain its use in dementia" by Ghayur MN, Gilani AH, Ahmed T, Khalid A, Nawaz SA, Agbedahunsi JM, Choudhary MI, Houghton PJ.(54)

C.3. Naringenin
Naringenin, a flavanone, belonging to the red, blue, purple pigments of Flavonoids (polyphenols) found predominantly in citrus fruits is considered as one of powerful antioxiant with many health benefits.
1. Antioxidant, radical scavenging and biomolecule activity
In the affirmation of the capacity of flavonoid naringenin and its glycoside naringin in the comparison of theirs antioxidant capacities, radical scavenging and biomolecule activities found that naringenin exhibited higher antioxidant capacity and hydroxyl and superoxide radical scavenger efficiency than naringin and both flavanones were equally effective in reducing DNA damage. However, they show no protective effect on oxidation of GSH, according to the study of "Antioxidant properties, radical scavenging activity and biomolecule protection capacity of flavonoid naringenin and its glycoside naringin: a comparative study" by Cavia-Saiz M, Busto MD, Pilar-Izquierdo MC, Ortega N, Perez-Mateos M, Muñiz P.(55)

Flavone, the isoflavones daidzein and genistein, the flavonols isorhamnetin, kaempferol and quercetin, the flavanone naringenin, and the anthocyanin pelargonidin amd theirs anti-inflammatory effects found that they inhibited iNOS protein and mRNA expression and also NO production in a dose-dependent manner, according to "Anti-inflammatory effects of flavonoids: genistein, kaempferol, quercetin, and daidzein inhibit STAT-1 and NF-kappaB activations, whereas flavone, isorhamnetin, naringenin, and pelargonidin inhibit only NF-kappaB activation along with their inhibitory effect on iNOS expression and NO production in activated macrophages" by Hämäläinen M, Nieminen R, Vuorela P, Heinonen M, Moilanen E.(56)

3. Immunity
In the unvestigation of Naringenin, a flavonoid in grapefruits and citrus fruits and its effec in immune system found that naringenin potently suppressed picryl chloride (PCl)-induced contact hypersensitivity by inhibiting the proliferation and activation of T lymphocytes. In vitro, both of the activated hapten-specific T cells and the T cells stimulated with anti-CD3/anti-CD28 showed growth arrest after naringenin treatment, according to "A novel regulatory mechanism of naringenin through inhibition of T lymphocyte function in contact hypersensitivity suppression" by Fang F, Tang Y, Gao Z, Xu Q.(57)

C.4. Tangeritin
Tangeritin, one of the flavones, is found in tangerine and many citrus peels
1. Neuroprotective effects
In the evaluation of neuroprotective effects of a natural antioxidant tangeretin, a citrus flavonoid and its effect on Parkinson's disease found that tangeretin crosses the blood-brain barrier. The significant protection of striato-nigral integrity and functionality by tangeretin suggests its potential use as a neuroprotective agent, according to "Tissue distribution and neuroprotective effects of citrus flavonoid tangeretin in a rat model of Parkinson's disease" by Datla KP, Christidou M, Widmer WW, Rooprai HK, Dexter DT.(58)

2. Antioxidants

Thyroid disease: Euthyroid sick syndrome as a result of Sepsis - The Risk Factors

Euthyroid sick syndrome
Euthyroid sick syndrome is defined as a condition of low T₃ low T₄ syndrome. According ot the study by the Mayo Clinic, in other word this is the abnormalities of thyroid hormone concentrations seen commonly in a wide variety of nonthyroidal illnesses, resulting in low triiodothyronine, total thyroxine, and thyroid stimulating hormone concentrations(a). Decreased triiodothyronine (T₃) levels are most common. Patients with more severe or prolonged illness also have decreased thyroxine (T₄) levels. Serum reverse T₃ (rT₃) is increased. Patients are clinically euthyroid and do not have elevated thyroid-stimulating hormone (TSH) levels(b). Causes of euthyroid sick syndrome include a number of acute and chronic conditions, including pneumonia, fasting, starvation, sepsis, trauma, cardiopulmonary bypass, malignancy, stress, heart failure, hypothermia, myocardial infarction, chronic renal failure, cirrhosis, and diabetic ketoacidosis and inflammatory bowel disease(c). Others, in the study of classified SES into 3 subgroups according to the different alterations seen in the values of T3, T4, FT3, FT4, TSH, rT3 and TBG suggested that in SES type I the diseases seen, in order of frequency, were: obstructive chronic bronchopneumopathy with acute respiratory failure, diabetic ketoacidosis, neoplasms, ischemic heart disease, cardiac failure, chronic renal failure, liver diseases, acute cerebral vasculopathies, sepsis and collagenopathies. The disease seen in the 2 cases of SES type II was obstructive chronic bronchopneumopathy with acute respiratory failure. In SES type III the diseases seen were, in order of frequency: diabetic ketoacidosis, lung diseases, ischemic heart disease, cardiac failure, peripheral arteriopathies, acute cerebral vasculopathies, neoplasms, liver diseases, acute renal failure(d).

Euthyroid sick syndrome as a result of Sepsis
Sepsis is defined as a condition caused by chemicals released into the bloodstream to fight the infection trigger inflammation throughout the body as a result of severe infection(a)(b). according to the study by the University of Utah, sepsis is the commonest cause of admission to medical ICUs across the world. Mortality from sepsis continues to be high. Besides shock and multi-organ dysfunction occurring following the intense inflammatory reaction to sepsis, complications arising from sepsis-related immunoparalysis contribute to the morbidity and mortality from sepsis(c).
The Risk factors of Sepsis
1. Term infants, while very low birth weight (VLBW) and preterm infants
According to the study by the Taipei City Hospital, total of 109 episodes of sepsis were identified in 100 neonates. The incidence of sepsis was 4.06% among all NICU admissions. Most neonates with early-onset sepsis were term infants, while very low birth weight (VLBW) and preterm infants accounted for the majority of cases of late-onset sepsis(14).

2. Obesity, operative vaginal delivery and age <25 years
In the study to describe the risk of maternal sepsis associated with obesity and other understudied risk factors such as operative vaginal delivery, found that ontrolling for mode of delivery and demographic and clinical factors, obese women had twice the odds of uncomplicated sepsis (OR 2.12; 95% CI 1.14-3.89) compared with women of normal weight. Age <25 years (OR 5.15; 95% CI 2.43-10.90) and operative vaginal delivery (OR 2.20; 95% CI 1.02-4.87) were also significant predictors of sepsis. Known risk factors for maternal sepsis were also significant in this study (OR for uncomplicated and severe sepsis respectively): multiparity (OR 6.29, 12.04), anaemia (OR 3.43, 18.49), labour induction (OR 3.92 severe only), caesarean section (OR 3.23, 13.35), and preterm birth (OR 2.46 uncomplicated only)(15).

3. Elder
If you are elder, you are at increased risk of sepsis

4. Patient in intensive care and with weakened immune system
Intra-abdominal infections are a common problem for the general surgeon and major sources of morbidity and mortality in the intensive care unit(16). Other indicated that severe sepsis has emerged as a major cause of admission and mortality for hospitalized HIV/AIDS patients, significantly affecting short- and longer-term survival of critically ill HIV/AIDS patients(17).

5. Invasive devices
There is a study of indwelling intravenous polyethylene catheters as factors influencing the risk of microbial colonization and sepsis(18).

6. Obesity and alcpholism
A multivariate analysis revealed that obesity (adjusted odds ratio [aOR] 21.4; 95% confidence interval [CI] 1.8-257.5) and alcoholism (aOR 6.5; 95% CI 1.3-32.8) were important predictive factors for spinal sepsis(18a).

Hydrocephalus Preventions - The Do's and Do Not's list

Hydrocephalus, also known as "water in the brain" is defined as complex and multifactorial neurological disorders of accumulation of cerebrospinal fluid (CSF) in the cavity of brain of that can lead to intracranial pressure inside the side, resulting of brain trauma, stroke, infection, tumor, etc.
Preventions
Other than structures abnormalities caused by genetic defects, accidence, etc., most acquired hydrocephalus can be prevented by enhancing the immune system in fighting against forming of free radicals causes of irregular cells growth and foreign invasion such virus and bacteria and reduce the risk of diseases cause of Hydrocephalus, such as dementia.
A. Do's and Do Not's list
1. Mediterranean diet
If you are typical American dieter, you are at increased to develop dementia when you get older as the diet is classified as one of the most unhealthy diet in the existence, as the study of ,researchers wrote in an older population of Southern Italy with a typical Mediterranean diet, high monounsaturated fatty acids energy intake appeared to be associated with a high protection against cognitive decline. In addition, dietary fat and energy in older people seem to be risk factors, while fish consumption and cereals are found to reduce the prevalence of AD in the European and North American countries(1). Also recent research supports the hypothesis that calorie intake, among other non-genetic factors, can influence the risk of clinical dementia.(29).

2. Yoga
Yoga is believed to have beneficial effects on cognition, attenuation of emotional intensity and stress reduction. In the study to evaluate the effects of yoga on memory and psychophysiological parameters related to stress, comparing yoga practice and conventional physical exercises in healthy men (previously yoga-naïve). Memory tests, salivary cortisol levels and stress, anxiety, and depression inventories were assessed before and after 6months of practice. Yoga practitioners showed improvement of the memory performance, as well as improvements in psychophysiological parameters(30). Other researchers at the G.J. Patel Ayurved College, showed that Mind and body are inseparable entities and influences each other until death. Many factors such as stress, anxiety, depression, negative thoughts, unhealthy life style, unwholesome diet etc., disturb mental and physical wellbeing. Senile dementia is the mental deterioration, i.e, loss of intellectual ability associated with old age. It causes progressive deterioration of mental faculties, e.g., memory, intellect, attention, thinking, comprehension and personality, with preservation of normal level of consciousness.(31). Other suggested that the effect of stress on the immune system and examine how relaxation techniques such as Yoga and meditation could regulate the cytokine levels and hence, the immune responses during stress(31a).

3. Aging of theory of mind
In the study to predict that educational level and cognitive processing are two factors influencing the pattern of the aging of ToM at Anhui Medical University, showed that the younger group and the older group with equally high education outperformed the older group with less education in false-belief and faux-pas tasks. However, there was no significant difference between the two former groups. The three groups of participants performed equivalently in the eyes test as well as in control tasks (false-belief control question, faux-pas control question, faux-pas control story, and Eyes Test control task). The younger group outperformed the other two groups in the cognitive processing tasks(32)

3. Moderate alcohol drinking
Moderate alcohol drinking of less than 2 cups for men and 1 cups for women are said to offers possible health benefits(3), but Binge drinking in midlife is associated with an increased risk of dementia, according to the follow-up, 103 participants had developed dementia. Binge drinking (ie, alcohol exceeding the amount of 5 bottles of beer or a bottle of wine on 1 occasion at least monthly), as reported in 1975, was associated with a relative risk of 3.2 (95% confidence interval=1.2-8.6) for dementia. Passing out at least twice as a result of excessive alcohol use during the previous year, as reported in 1981, was associated with a relative risk of 10.5 (2.4-46) for dementia in drinkers.(33). Other in the study to evaluated how (1) the number of alcoholic drinks the subjects consumed per month and (2) the drinking cessation of certain subjects were associated with their relative and absolute T, B, CD4, and CD8 lymphocyte counts and immunoglobulin A (IgA), IgM, and IgG levels, indicated that indicated that measures of immune status differed among the drinking categories and that, generally, the differences changed after adjustment for covariates. These differences consisted, as alcohol consumption increased, of higher IgA and IgM levels, relative T and CD4 lymphocytes, and the ratio of CD4 to CD8 cells, and of lower IgG levels, relative B and CD8 lymphocytes, absolute lymphocyte, and lymphocyte subset counts after adjusting for other covariates(33a).

4. Stop Smoking or never smoke before
Smoking is a risk factor for several life-threatening diseases, but its long-term association with dementia is controversial and somewhat understudied.In a studyof a total of 5367 people (25.4%) were diagnosed as having dementia (including 1136 cases of AD and 416 cases of VaD) during a mean follow-up period of 23 years. Results were adjusted for age, sex, education, race, marital status, hypertension, hyperlipidemia, body mass index, diabetes, heart disease, stroke, and alcohol use, Dr. Rusanen M, and the team at the University of Eastern Finland, said " heavy smoking in midlife was associated with a greater than 100% increase in risk of dementia, AD, and VaD more than 2 decades later. These results suggest that the brain is not immune to long-term consequences of heavy smoking"(34).

5. Drink you tea and coffee
Caffeine in tea and coffee may enhance cognitive function acutely. In Aging and Dementia (CAIDE) study, the findings of the previous studies are somewhat inconsistent, but most studies (3 out of 5) support coffee's favorable effects against cognitive decline, dementia or AD. In addition, two studies had combined coffee and tea drinking and indicated some positive effects on cognitive functioning. For tea drinking, protective effects against cognitive decline/dementia are still less evident. In the CAIDE study, coffee drinking of 3-5 cups per day at midlife was associated with a decreased risk of dementia/AD by about 65% at late-life. coffee(35). Others in the study of Immunomodulatory effects of decaffeinated green tea (Camellia sinensis) on the immune system of rainbow trout (Oncorhynchus mykiss), showed that decaffeinated green tea in lower doses of administration could be optimum to enhance the immunity of rainbow trout(36a).

6. Eat you fruits and veggies
Fruits and veggies contains high amounts of antioxidant which enhance the immune system in fighting against forming of free radicals in which can cause damage to the brain cells of that lead to dementia. Researchers at The Johns Hopkins University indicated that use of vitamin E and vitamin C supplements in combination is associated with reduced prevalence and incidence of AD. Antioxidant supplements merit further study as agents for the primary prevention of AD(36).

7. Regular exercise and moderate exercise for elder
In the study to evaluate to the effects of regular exercise versus a single bout of exercise on cognition, anxiety, and mood were systematically examined in healthy, sedentary young adults who were genotyped to determine brain-derived neurotrophic factor (BDNF) allelic status, indicaed that altered activity-dependent release of BDNF in Met allele carriers may attenuate the cognitive benefits of exercise. Importantly, exercise-induced changes in cognition were not correlated with changes in mood/anxiety, suggesting that separate neural systems mediate these effects(37). Other indicated that Overall, in healthy older adults, regular, particularly aerobic, exercise appears to be a friend of the immune system, helping to offset diminished adaptive responses and chronic inflammation. The possibility exists that particularly strenuous exercise may cause acute immunologic changes, such as diminished NK cell activity, which could predispose to infection in certain individuals(37a)

8. Avoid nutritional deficiency with balance diet
Beyond our believe, in the study to highlight how an excess of dietary carbohydrates, particularly fructose, alongside a relative deficiency in dietary fats and cholesterol, may lead to the development of Alzheimer's disease and a first step in the pathophysiology of the disease is represented by advanced glycation end-products in crucial plasma proteins concerned with fat, cholesterol, and oxygen transport.(38). Dr Pae M, and the research team at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University, suggested that the need for a more in-depth, wholestic approach to determining the optimal nutritional strategies that would maintain a healthy immune system in the elderly and promote their resistance to infection and other immune-related diseases(38a).

9. Avoid environment risk of dementia(39)
Certain environment toxins produced as a result of industrialization or naturally have been linked to cognitive degenerative diseases. Researchers at the University of British Columbia in the investugation of Novel environmental toxins: steryl glycosides as a potential etiological factor for age-related neurodegenerative diseases, showed that Mice fed washed cycad flour show signs that mimic ALS-PDC, which include progressive deficits in motor, cognitive, and olfactory functions associated with neuron loss in the spinal cord, nigrostriatal system, cortex, hippocampus, and olfactory bulb. Through a series of chemical extractions of washed cycad flour, we identified steryl glycoside molecules as bioactive molecules that are neurotoxic in culture and in mice. A detailed review of this class of molecule revealed that the molecules are abundant in the environment, particularly in plants and bacteria. Lipid analysis showed that some bacteria that are associated with some forms of neurodegenerative disorders have the capacity to synthesize steryl glycosides. Furthermore, certain steryl glycosides have been found to be a cell stress mediator and may have some immunomodulary effects. Others researchers showed that Parkinson disease (PD) and Alzheimer disease (AD), are of purely genetic origin in a minority of cases and appear in most instances to arise through interactions among genetic and environmental factors and early environmental origins of neurodegenerative disease in later life. Also environment toxins can reduce the immune function in protecting against other diseases.

10. No illicit drug, please(40)
Illicit drug used may cause nervous system impairment as a result of direct and indirect effects on the integrity and function of nervous system tissue and, potentially, through immune effects. HIV-1 infection poses an additional risk of impairment, and this risk may be decreased as a result of antiretroviral drug treatment. Others researchers suggested that injection drug use represents the primary risk factor for up to 40% of patients with HIV infection. Illicit drug also can effect the CNS and weaken the immune system.

11. Prevent prolonged period of using certain drug(41)
As aging, accumulation of toxins of certain medication used to treat certain diseases, such as antidepressants, sedatives, cardiovascular drugs and anti-anxiety medications may cause increased risk of cognitive dysfunction leading to produced dementia-like symptoms. Certain medication can suppress the immune system.

Hydrocephalus - Diagnosis

Some suitable tests of this type are :

2.1 The grooved pegboard test

2.2. The Stroop test

2.3. The digit span test

2.4. The trail-making A/B test

2.5. The Rey auditory-verbal learning test

3. For patients with Incontinence

Disturbances of bladder function in NPH result from detrusor hyperactivity owing to the partial or total absence of central inhibitory control. Patients initially suffer from increased urinary frequency (– ); later developments are urge incontinence and, finally, permanent urinary incontinence. Fecal incontinence is rare in NPH (2) and should arouse suspicion of another type of neurodegenerative disease. If present in a patient with NPH, it implies severe frontal subcortical dysfunction.

CSF shunting can improve bladder dysfunction in as many as 80% of iNPH patients if performed early, but in no more than 50% to 60% if performed in an advanced stage of the disease (e15, , ).

4. NPH and other neurodegenerative disorders

Findings that make NPH less likely

4.1. Asymmetrical findings

4.2. Cortical deficits, e.g., aphasia, apraxia, paresis

4.3. Progressive dementia without gait disturbance

4.5. Lack of progression of symptoms

B.2. General Diagnosis and tests

1. Computerized tomography (CT) or magnetic resonance imaging (MRI)

Either computerized tomography (CT) or magnetic resonance imaging (MRI) of the brain is necessary—yet, alone, never sufficient to establish the diagnosis of NPH.

2. Invasive diagnostic testing

The aim of the tests is needed to raise the prognostic accuracy above 80%

2.1. Spinal tap test: lumbar puncture with the removal of 30 to 70 mL of CSF. This can be repeated on two or three consecutive days

2.2. Continuous spinal drainage of 150 to 200 mL of CSF per day for 2 to 7 days (1– 2)

If the number of steps taken in a 10 m gait test, and the time needed to walk 10 m, are reduced by at least 20%, and/or psychometric tests show an improvement of at least 10%.

3. Other invasive tests

Long-term ICP measurement for 24 to 72 hours is performed in no more than a few centers. Special pressure waves and brain pulse amplitudes are measured Such techniques are not recommended for routine use, both because their predictive value has not yet been sufficiently documented and because they require specialized equipment and expertise.
