Dementia refers to a range of disorders that affect the brain. People with dementia typically have problems with thinking, reasoning, and problem solving.

Dementia can have a severe effect on memory, and some of its varieties can also lead to physical disabilities such as Parkinson's disease.
Metabolic conditions, endocrine issues, nutritional deficiencies, and infections are some of the causes of different types of dementia.
While older people are more likely to experience dementia, it is not part of the ageing process and can affect younger people too.

Forgetfulness is one sign of some kinds of dementia.
Different types of dementia will share some symptoms, but other symptoms will be specific to the disease. These are some of the main types of dementia.
Alzheimer's diseaseAccording to the Alzheimer's Association, Alzheimer's disease is the most common dementia type, affecting between 60 and 80 percent of all people with dementia.

A doctor cannot officially diagnose a dementia type as Alzheimer's, because they must view specific nerve cell damage in the brain that can only be examined after a person dies.
In the early stages, people with Alzheimer's typically have difficulty remembering recent events or conversations, as well as names of people. They may also experience depression.
In time, people find it increasingly difficult to communicate, and their judgment may become impaired. They may feel disoriented and confusion. Their behavior could change, and physical activities such as swallowing and walking might become harder.
Creutzfeldt-Jakob diseaseThis condition represents a number of brain diseases that are believed to be triggered by prion proteins, which cause problems throughout the body. Although a prion is neither a virus nor a bacterium, it can cause a disease.
Types of Creutzfeldt-Jakob disease include "mad cow disease." The condition causes rapid memory, behavior, and movement changes. It is a rare and fatal condition.
Dementia with Lewy bodiesThe symptoms can be similar to those of Alzheimer's disease, but people who have dementia with Lewy bodies may also experience sleep disturbances, visual hallucinations, and an unsteady walking pattern.
Frontotemporal dementiaThis condition can trigger changes in how people behave and how they relate to others. It can also cause problems with language and movement.
Frontotemporal dementia typically tends to appear in an individual at around 60 years of age, but it can appear as early as the 20s. It involves a loss of nerve cells.
Parkinson's diseaseParkinson's is a motor system disorder. The hallmark signs include trembling, especially tremor in the hands. It can also involve depression and behavioral changes.
In the later stages, the individual may have difficulty speaking. Sleep disturbances might also occur.
Huntington's diseaseHuntington's is a genetic disorder that results from a defect on chromosome 4. It can lead to mood changes, abnormal movements, and depression.
The person may experience an ongoing decline in thinking and reasoning skills. There could be slurred speech and problems with coordination. It tends to appear in individuals aged between 30 and 50 years old.
Mixed dementiaMixed dementia occurs when a person has dementia due to more than one cause, such as Lewy body dementia and vascular dementia, or Alzheimer's disease.
Normal pressure hydrocephalusThis condition results when cerebrospinal fluid builds up in the brain, therefore causing pressure.
Symptoms can include memory loss, problems with movement, and the inability to control urination. It can happen at any age, but it is more common among older people.

Vascular dementiaAlso known as post-stroke dementia, this condition occurs after a person experiences bleeding or vessel blockage in the brain, known as a stroke. It affects a person's thinking and physical movements.
According to the Alzheimer's Association, early symptoms may include an inability to organize, plan, or make decisions.
Wernicke-Korsakoff syndromeThis condition occurs due to a chronic deficiency of vitamin B1 or thiamine. It is most common in those who chronically abuse alcohol. The effects of alcohol and a poor diet are likely to contribute to the development of the condition.
The chief symptom is severely impaired memory, including long-term memory gaps, which the person may try to fill in with incorrect versions of what they think happened. This unintentional lying is known as confabulation.
