Alzheimer's Disease.

Alzheimers Disease Alzheimers Disease (AD) is a chronic, degenerative disease that is characterized by the red ink of cognition. AD that occurs before the progress of 60 is known as pre- senile dementia. If AD occurs after(prenominal) the age of 60, it is known as senile dementia. AD accounts for more than than than 60% of all(a) dementias (Tabers 81). AD is the ...process of cordial wasting plot motor functions remain inbuilt (Tyrer 215). Be movement of this psychogenic wasting, AD in late stages tends to be more rocky for the family of an AD patient, or else then the patient themselves. Although the cause of AD is unknown, the risk factors take family history of dementia and aged(prenominal) age. There are three stages of AD progression. gunpoint I (mild dementia) is characterized by freeing of short barrier memory and decrease judgment. academic degree II (moderate dementia) includes difficulty with language and language, personality changes, wandering, depression, paranoia and hallucinations. In Stage terce (severe dementia) the patient looses the natural endowment to perform activities of daily reenforcement and requires 24 hour fretfulness (Tabers 82). AD is diagnosed typically by eliminating separate causes of dementia. In later stages of AD, an magnetic resonance imaging may show a decline in the sizing of the cortex (Treatment 4). The major pathology of AD is the depravity of cortical neurons. The enzyme acetyltransferose is decreased in the cortex.

This decrease is joined with a reduction in available acetylcholine, an important neurotransmitter (Tyrer 215). This lose of acetylcholine is dissociate of the cause of cognitive impairment. Nuerofibrillary tangles (twisted fragments of protein within nerve cells) and neuritic plaques (abnormal clusters of pulseless and decease nerve cells) also occur in patients with AD (Tabers 81). The prognosis for patients with AD is unfortunate. Patients with AD eventually loose all ability to care for themselves. last normally...
