Dementia is the loss of cognitive functioning—thinking, remembering, and reasoning—and behavioral abilities to such an extent that it interferes with a person’s daily life and activities.Dementia affects thinking, behaviour and the ability to perform everyday tasks. Brain function is affected enough to interfere with the person’s normal social or working life.

Most people with dementia are older, but it is important to remember that not all older people get dementia. It is not a normal part of ageing. Dementia can happen to anybody, but it is more common after the age of 65 years. People in their 40s and 50s can also have dementia

Dementia ranges in severity from the mildest stage, when it is just beginning to affect a person’s functioning, to the most severe stage, when the person must depend completely on others for basic activities of living.

• Alzheimer’s dementia/Alzheimer’s disease (AD): It ) is the most common form of dementia. Alzheimer’s disease begin after the age of 65, in some cases symptoms begin when someone is in their 40s or 50s. This early onset Alzheimer’s disease can progress more rapidly than later onset AD.
• Vascular dementia: It is the second most common cause of dementia, and is due to multiple strokes occurring within the brain. Patients with untreated high blood pressure or heart disease may be at risk of developing vascular dementia.
• Frontotemporal dementia: forgetfulness and word finding problems, patients may have marked personality changes, impulsivity, or poor judgment. Some patients with frontotemporal dementia can develop incoordination or stiffness of their muscles.
