Not coping well.

You may have difficulty accepting changes to schedules or the environment.

Subtle changes in the creation of short-term memory.

You or one of your relatives remembers the events of 15 years ago as if it were yesterday, but you do not remember what you had for lunch.

Collecting or linking words can be more difficult.


You can ask the same question, do the same thing, or tell the same story several times.

Sense of confused orientation.

The places you knew well before can seem strange to you. You may also have problems with the routes you have traveled for years because you are no longer known.

It can be difficult to trace a person's history or description.

Mood changes.

Causes of Dementia

The most common causes of dementia are:

Neurological degenerative diseases.

Vascular Diseases

These are disorders that affect the bloodstream in your brain.

Traumatic brain

The injury caused by car accidents falls, concussions, etc.

Infections of the central nervous system. 

These include meningitis, HIV and Creutzfeldt-Jakob disease. Prolonged consumption of alcohol or drugs. Some types of hydrocephalus, an accumulation of fluid in the brain

Risk Factors of Dementia

Age, however, is the greatest predictor. Other risk factors are:

  • Smoking and consuming alcohol

  • Atherosclerosis (a cardiovascular disease that narrows the arteries).

  • High content of "bad" cholesterol (low-density lipoproteins).

  • Blood levels above average for homocysteine (a type of amino acid).

  • Diabetes

  • A mild cognitive impairment sometimes, but not always, leads to dementia.

Types of Dementia

There are several types of dementia, including:

Lewy body dementia

Lewy body dementia is a neurodegenerative disease associated with abnormal structures in the brain. Brain changes include a protein called alpha-synuclein.

Mixed dementia

Mixed dementia refers to a diagnosis of two or three types that occur together. For example, a person may have Alzheimer's disease and vascular dementia simultaneously.

Parkinson's disease

Parkinson's disease is also characterized by the presence of Lewy bodies. Although Parkinson's disease is often considered a movement disorder, it can also cause dementia symptoms.

Huntington's disease

Huntington's disease is characterized by some types of uncontrolled movement but includes dementia.

Other disorders that lead to symptoms of dementia are:

Frontotemporal demen

Frontotemporal dementia also called Pick's disease.

Hydrocephalus at normal pressure when excess cerebrospinal fluid accumulates in the brain.

The posterior cortical

The posterior cortical atrophy is similar to the changes in Alzheimer's disease but in another part of the brain.

Down's syndrome
