Dementia is a loss of brain function. It is not a single disease. Instead, dementia refers to a group of illnesses that involve memory, behavior, learning, and communicating problems. Dementia usually affects older people and becomes more common with age. About 6 in 100 of those over the age of 65 will develop some degree of dementia. Dementia affects about 1% of people aged 60-64 years and as many as 30-50% of people older than 85 years. Memory loss is a common symptom of dementia. The symptoms of dementia can vary greatly. Memory loss is a common symptom of dementia.
Other symptoms of dementia include problems with speech and language , Confusion ,Changes in mood or behaviour amd difficulty performing simple tasks they may have difficulty doing everyday tasks such as cooking a meal. Dementia with Lewy bodies (DLB) is a leading cause of degenerative dementia in elderly adults. This condition is linked to abnormal protein structures in certain areas of the brain. The structures and symptoms of DLB are associated with Alzheimer's disease. Treatable causes of dementia include normal pressure hydrocephalus, brain tumors, and dementia due to metabolic causes, low vitamin B12 levels, and infections.
There are a number of favourable conditions which can ease the situation of the patient and his/her relatives - these conditions concern in particular the actual care and the organisation of the environment. Treatment may include a combination of drug and psychiatric or behavioral therapies. Exercise, both physical and mental, can slow the progress of dementia. Phosphatidylserine (100 mg 3 times per day), a substance occurring naturally in the brain, shows promise in several studies. Do not take phosphatidylserine if you are taking blood-thinning medication, and use caution if combining it with ginkgo for the same reason.
Essential fatty acids, such as those found in alpha linolenic acid (ALA), borage oil, and evening primrose oil, may help reduce the risk of Alzheimer's disease. Omega-3 fatty acid docosahexaenioc acid (DHA) in the blood can significantly lower the risk of dementia. Zinc (30 - 50 mg per day) is often deficient in elderly people, and may help improve memory. Dietary changes include eating less animal fats and more fish. Antioxidants may protect against the development of dementia. They may even slow the progression of dementia, especially vitamin E (400 - 800 IU per day) and vitamin C (1,000 mg three times per day) taken together.
