Dementia is a non-specific term to cover those disorders marked by a serious loss of cognitive ability, and resulting in serious problems of memory, language, attention, and problem solving. Any stage of adulthood may be the onset age of Dementia. However, it is far more common in the geriatric population. Alzheimer’s disease is the most common and frequent specific form of dementia in clinical medicine.

The symptoms and signs of Dementia vary, according to the variousunderlying causes. Common manifestations of all dementias include:

  • Memory loss
  • Impaired ability in learning
  • Impaired ability in communicating
  • Impaired ability in reasoning
  • Poor coordination and motor functions
  • Personality changes

Some patients may experience agitation, paranoia, or hallucinations. Dementia can also cause difficulty with planning and organizational thinking. In the later stages, it will likely cause disorientation of time, place, and person.

Most types of dementia have no known cure. Present treatments are focusing on improving the symptoms and slowing the progression of Dementia. Medications (such as certain cholinesterase inhibitors) may be useful for treating the symptoms. Cell therapy may also be useful.
