Alzheimer’s Disease
What exactly is Alzheimer’s Disease?
 Alzheimer’s
disease is a progressive neurodegenerative disease characterized by
progressive memory loss, poor judgment, language deterioration, and
impaired visuospatial skills. Alzheimer’s disease usually begins
after the age of 65 but may occur as early as (early onset type) 40
years old. It usually begins with minor impairment in short-term
memory with such experiences as frequently losing keys, and eventually
progresses to include severe short-term and long-term memory loss, as
well as affecting most other areas of an individual’s cognitive
functioning. Alzheimer’s disease eventually destroys cognition,
personality and ability to function. In the earliest stages it may be
difficult to differentiate from normal aging, but as it progresses it
simply and individuals total ability to function.
How would an individual get Alzheimer’s?
There continues to be extensive research in this
area to determine how individuals contract the disease. Current
research indicates that there are two main categories associated with
the etiology of Alzheimer’s disease, including the familial and
sporadic. Familial Alzheimer’s disease is a genetic form which is
transmitted from one generation to the next. Approximately 5 % of all
case of Alzheimer’s disease have been associated with a genetic
component. These individuals frequently come from families where as
many as half of the family members may develop the disease. This form
of the disorder is rare, however. The remaining 95 % of Alzheimer’s
disease cases are sporadic, randomly occurring in the population. At
the present time, particular dietary habits, professional occupations
and specific personality types do not appear to lead the development
of the disease.
Signs and symptoms of Alzheimer’s Disease and
prognosis:
Early-stage Alzheimer’s symptoms can also be very
similar to those which result from fatigue, illness, vision or hearing
loss, grief, depression or the use of alcohol and various medications.
However, Alzheimer’s symptoms become progressively worse over time,
eventually destroying short-term memory, concentration, long-term
memory, judgment and personality. The primary symptoms include
multiple cognitive deficits manifested by memory impairment and other
cognitive disturbances, including language disturbances, impaired
ability to carry out motor (physical) activities despite intact motor
function, failure to recognize and identify simple objects and
disturbances in executive functioning. The cognitive deficits must
cause significant impairment in social or occupational functioning and
represent a significant decline from previous functioning.
Alzheimer’s disease is progressive in nature, but
its course may vary from individual to individual. some individuals
may have it for sure appear in time and the last five years of their
life while others may have it offers many as 20 years. Most common
cause of death in Alzheimer’s patients is infection.
Treatment and research:
Currently there is no cure for Alzheimer’s
disease and no sure way to limit its progression. Some people in the
early to middle stages of the disease, find medications such as
tacrine (Cognex), Aricept (donezepil) and Exelon (rivastigmine) slow
the progression.other medications are also used to control the
behavioral symptoms associated with Alzheimer’s disease such as
aggression, sleeplessness, wandering common anxiety. Also, frequently
environmental and behavioral modification are effective in reducing
the effects of an over-stimulating environment, along with basic
behavioral modification techniques to improve specific behaviors.
Current research includes searching for the cause
or etiology, as well as developing a vaccine which is aimed at
preventing or reversing the formation of Alzheimer’s
disease-associated pathologic lesions. Recent results using a
transgenic mouse model suggests that immunological interventions may
slow or reverse the development of some of the pathogical changes
associated with Alzheimer’s disease. Early clinical trials are
hopeful but currently are still very tentative.
