Clinical Features (Symptoms)
Alzheimer’s disease is a progressive disease that gradually destroys brains cells affecting brain functions. Scientists explain that Alzheimer’s disease progresses on a spectrum with three stages from an early stage to a middle stage of mild cognitive impairment (MCI) and to a final stage of Alzheimer’s dementia. Not everyone experiences the same progress at the same rate and the symptoms will develop over the same general stages.
The early state symptoms of Alzheimer’s disease include increased forgetfulness, mind confusion, getting lost, poor judgment and thinking problems. Most of people with AD in early stages will have hard time remembering recent memories or certain thing, notice slowed thinking process.

The changes and the signs of dementia may be more noticeable to family member, close friends or co-workers. However, microscopic changes in the brain due to Alzheimer’s disease will begin long before first sign of memory loss.
As Alzheimer’s disease progresses the symptoms will gradually get worse. In the moderate stage of Alzheimer’s disease, damage occurs in areas of the brain that are responsible for controlling language, reasoning, sensory processing and conscious thought. At this stage, people with AD will have problems recognizing family and friends, difficulty learning new things and may wander and get lost. They may repeat statements and questions over and over without realizing that they have done it before and may not be able to perform basis tasks that involve multiple steps such as getting dressed or taking a bath.
