Alzheimer's Disease

ALZHEIMER"S DISEASE 
Alzheimer's disease is a part of a brain disease. the onset of the symptoms are gradual, but the Alzheimer's disease grows slow and steady and ruins ones brains' memory. during the AD the person needs to go through a serious problems. For example,  the person can have a speaking difficulty, or unable to understand a language. All around the world, the AD occurs mostly at over the age of 80. This AD doesn't affect all the memory of the brain, it just effects the episodic memory. this episodic memory is the memory of events and personal experiences. The AD also affects the semantic memory, which is the memory stored in general knowledge about the world concepts and language.
Through the Ad video I learned that memories are who we are and if the AD occurs the memory will come to a lose. There is no treatment right now about the AD. The changes in brain will change the personality of the person. the family members of the AD patient will have to be the family care giver, and should take care of the AD patient. Also the AD will bring the lose of synopsis.
through the video I had a feeling that it is a natural event that can occur, suddenly, and got afraid of the disease, and I hope scientists and psychologists will find a way of curing the diseases. Right now, the scientists are trying a way out of the Alzheimer's disease, but they say that it is really hard. Alzheimer's disease that effect the brain is a problem and we need a way out of the situation.
