Alzheimer's Disease

Alzheimer's disease is a neuropsychiatric disorder caused by loss of structure or function or even death of neurons in the brain, which results in memory loss, speech impairment, mood swings, disorientation, and in most cases dementia.

It is a progressive disease, whose first symptoms seem as typical as the early signs of ageing, e.g. forgetfulness, lack of focus, short-term memory loss, depression, and fretfulness. During the advanced stages of Alzheimer, the patient experience severe loss of explicit memory, i.e. the ability to recall recent information, and some loss of the implicit memory, i.e. the long–term memory acquired subconsciously. This means during the advanced stages of the disease, the patient becomes entirely dependent on the caretaker since the ability to perform many basic activities of daily life like eating, walking, and talking is also lost.


The exact cause of the disease is mostly unknown. However, genetics, head injuries, stress, depression, and hypertension are identified to increase the risk of getting Alzheimer's.

Although no medication has been able to cure or even delay the progression of the disease, some medicines are available on the advice of a doctor.
