Dementia
Dementia is defined as neuro degeneration syndrome among elder, affecting memory, thinking, orientation, comprehension, calculation, learning capacity, language, and judgement over 47 millions
of worldwide population, mostly in the West. The evaluation of the syndrome by holistic medicine has been lacking, especially through conventional medicine research and studies.
Types of dementia
1. Alzheimer's disease
1. Alzheimer's disease
Alzheimer's disease is a brain disorder named for German physician Alois Alzheimer(1). Alzheimer's destroys brain cells, causing problems with memory, thinking and behavior severe enough to affect language communication, memory, lifelong hobbies or social life. Alzheimer's gets worse over time, and it is fatal(2). Over 1 million people in US alone are currently afflicted by Alzheimer's disease because of degeneration of hippocampus and cerebral cortex(3) of the brain where memory, language and cognition(4) are located. With this mental disorder, brain cells gradually die and generate fewer and fewer chemical signals day by day resulting in diminished of functions. Overtime memory thinking as well as behavior deteriorates. Today, there is no known cure.
2. Absence of acetylcholine
If the nerves located in front of the brain perish(5), caused by diminished quality of acetylcholine due long term alcohol abused may result of cognitive dysfunction(6) causes of language difficulty, memory loss, concentration problem, and anxiety- and depression-like behaviors(8),reduced moblile skills because of lacking reaction in muscular activity and refection(7).
3. Dementia due to long-term alcohol abuse
Dementia is common in patients with alcoholism(9). Most classic is the Korsakoff's dementia resulted in extremely poor short term memory(10) and often associated with the memory losses of confabulations due to diminished processing resources and/or an encoding or retrieval deficit(11).
4. Multi-infarct dementia
Also known as vascular dementia, is the second most common form of dementia after Alzheimer's disease in older adults caused by different mechanisms all results in vascular lesions(12) of the brain(13).
5. Dementia associated with Parkinson's disease
Parkinson disease (PD) is a disabling, progressive condition, causes of cognitive deficits due to the interruption of frontal-subcortical loops that facilitate cognition and parallel the motor loop(15)(16) due to loss of substantia nigra pars compacta (SNc) dopamine (DA) neurons(14).
6. Creutzfeldt-Jakob disease (CJD)
People who have eaten contaminated beef(18) for many years may be infected without even knowing it. Creutzfeldt-Jakob disease is a quickly progressing and fatal disease consisted of dementia(19), muscle abnormal functions(17).
7. Subdural hematoma
It is the accumulation of blood beneath the outer cover of the brain resulted from the rupture of blood vessel(20)(21). Subdural hemorrhages may increase intracranial pressure(22), causing compression and damage to delicate brain tissue. Acute subdural hematoma has a high mortality rate(23).
Other types of dementia include metabolic disorders, dementia due to long-term substance abuse, hypothyroidism, and hyperethyroidism.
