Dementia is a common disease, affecting about 4 million people alone in the United States. It is the major cause of long term disability in old age. The prevalence of dementia increases rapidly with age, afflicting about 2 percent of the population between ages 65 and 70 and 20 percent of people above 80.
With increasing longevity of the population and decreasing birth rates, the prevalence will continue to rise.

Most diseases causing dementia are either widespread neuronal degeneration or multifocal disorders. The initial symptoms depend on where the dementing process starts, but the location and number of neurons lost that are required to cause dementia are difficult to establish. Aging results in a gradual loss of neurons and of brain mass, but this is not accompanied by significant intellectual decline in the absence of disease.
Dementia may result form cortical disease (e.g. Alzheimer's disease) or from disease of sub cortical structures such as the basal ganglia, thalamus and deep white matter (e.g. Huntington's disease or multiple sclerosis). Cortical dementia is characterized by loss of cognitive function such as language, perception, calculation; in contrast, sub cortical dementia exhibits slowing of cognition and information processing, flattening of the affect, and disturbances of motivation, mood and arousal. Memory is impaired in both types. The features of sub cortical dementia also occur in cortical processes affecting the frontal lobes and probably reflect damaged projections to and from the frontal lobes.
In Alzheimer's disease, which is the most common cause of dementia, the dementia results from loss of cortical tissue especially in the temporal, parietal and frontal lobes. This is accompanied in most cases by increased space between the gyri and enlargement of the ventricles.
Plaques and tangles are found in normal elderly brains but are increased in number in Alzheimer's disease, especially in the hippocampus and temporal lobes. The hippocampal involvement probably accounts for the memory disorder, which may be partially mediated by a reduction in cholinergic activity.
The activities of other neurotransmitters, including nor-ephrine, serotonin, dopamine, glutamate, and somatostatin are also reduced. These changes are accompanied by reductions in cerebral blood flow and decreased metabolism of oxygen and glucose.
The causes of dementia are numerous. However, a small number of diseases account for most cases. In most of the western world, Alzheimer's disease is responsible for 50 to 90 percent and vascular disease for 5 to 10 percent of cases of dementia referred to hospital.
In HIV infection, dementia occurs in 30 to 40 percent of patients and is an important cause in youngster patients.
The main aim of diagnosis is to identify treatable causes of dementia. The differential diagnosis depends primarily on a careful history and examination, supported by investigation.
Vascular dementia results from multiple areas of discrete infarction and not from chronic diffuse ischemia. The diagnosis of vascular dementia is strongly suggested by an abrupt onset, especially if there is a history of previous stroke. Hypertension is usual in vascular dementia but rare in Alzheimer's disease.
There are various herbs that are useful in improving brain function and learning. Brahmi, Vacha, Jatamansi, Shankhpushpi, American Ginseng, Gingko biloba are the various herbs useful in improving the brain functions. These herbs also useful in reducing the nervous disorders like stress, anxiety etc.
