The Early Signs and Symptoms of Dementia

Written by Dr. Agatha and medically reviewed by iCliniq medical review team.


Dementia does not indicate a specific disease but is a medical term to describe a group of symptoms associated with memory loss as well as thinking and reasoning skills. The condition is severe enough to limit the person's ability to perform everyday activities. Alzheimer's disease is the most severe form of dementia and accounts for 60 to 80 percent of cases.


The early symptoms include forgetfulness, confusion, and the inability to recognize common things. The person may experience a decline in cognitive abilities such as memory loss, mental decline, and confusion, especially in the evening hours.

There is disorientation, inability to speak or understand a language and making up things. Another common symptom is limited social skills and loss of clear thinking abilities.

  • Behavioral: There is a feeling of irritability, personality changes, restlessness, lack of restraint or wandering and getting lost.
  • Mood: There is anxiety, loneliness, mood swings or nervousness.
  • Psychological: The person is depressed, has hallucinations or is paranoid.
  • Muscular: There is an inability to combine muscle movements with an unsteady gait. While walking, they fall commonly.
  • Speech: They have a jumbled speech and repeat their words a lot.
  • Sleep: There is disturbed sleep or a sleep disorder.


Dementia requires a medical diagnosis mainly made through history from the person or the guardian about any of the behavioral changes and other symptoms discussed above.

There are a few laboratory tests or imaging tests that may be required if the doctor wants to rule out the cause.


Severe dementia has no cure, but in early dementia, some medications and therapies may help reverse the symptoms. Other severe forms of dementia have no cure.


if you or your loved ones are experiencing the symptoms of dementia, try to seek medical help from a healthcare professional who is specialized in this field.
