7.1 Pathologies Related to Memory

There are two major types of memory disorders that are caused by problems in the functioning of the memory areas of the human brain. They are called retrograde amnesia and anterograde amnesia.

Retrograde amnesia occurs in people who have met with accidents leading to head injury. They are unable to recall the accident or fail to remember the last several hours or even days before the occurrence of the accident. It is called retrograde because the loss of memory is for events that occurred before the traumatic event.

The anterograde amnesia refers to the inability to store new information after a trauma or accident. Such people have difficulty remembering any new information. It is often found in people with senile dementia in which older people suffer from severe forgetfulness and mental confusion.

Alzheimer’s disease is the most common form of dementia found in adults and elderly. It is a brain disorder that affects a person’s ability to carry out everyday activities. The most common form of this disorder often found among the older people is ‘Alzheimer’s Disease’ (AD) which involves areas of the brain that control thought process, memory and language. AD was named after, Dr. Alex Alzheimer, a German doctor in 1906. At present there is no cure for AD. However, new medicines are showing some positive results.
