Alzheimer's disease is a degenerative disease, getting worse as the disease progresses. The rate at which this happens may vary among individuals, as many experience problems in their memory and daily lives at an early stage in the disease while others may perform quite well until later in the disease.

Alzheimer's is caused by the loss of neurotransmitters in the brain. These act as chemical messengers, carrying messages throughout the brain and as their numbers decline, the ability of the brain to communicate within itself is diminished.

Common symptoms of Alzheimer's disease may include difficulty making decisions, confusion regarding what time it is and what day it is, getting lost in otherwise familiar places, trouble retaining and learning new information, trouble formulating sentences to convey thoughts or ideas and difficulty performing other daily tasks. Sufferers of Alzheimer's may experience a worsening of their symptoms overtime, but if the symptoms suddenly appear or worsen, the patient should consult a physician.

Additionally, Alzheimer's patients may grow restless and wander aimlessly in the afternoon or evening in a condition called sundowning. Other symptoms may include seclusion from family and friends, paranoia and a tendency to lash out at others.

Alzheimer's disease has no cure, but treatments do exist that may slow the disease or make life easier for patients. A doctor may prescribe medication to help with a patient's memory and ability to think effectively.

Also, medication that may help a patient's memory loss or confusion may be prescribed as well. Treatment for depression, if it is present, may also be prescribed. These treatments may not work for all patients and the results may vary.
