Overview

Dementia is a condition that affects memory, thinking, and the ability to perform daily activities. It happens when brain cells are damaged, leading to problems like forgetting recent events, getting lost, or having trouble finding the right words. The most common type is Alzheimer’s disease, which mainly affects older adults. Another form is vascular dementia, which occurs when blood flow to the brain is reduced, often due to a stroke.

Our approach

Dementia is a general term for a decline in cognitive function severe enough to interfere with daily life. It involves problems with memory, thinking, reasoning, and behavior. While Alzheimer's disease is the most common cause, dementia can result from various conditions that damage brain cells or affect brain function.

Symptoms

The symptoms of dementia can vary depending on the cause and stage of the condition but often include:

  • Memory Loss: Especially recent events, names, and appointments.
  • Difficulty Communicating: Struggling to find the right words or follow conversations.
  • Disorientation: Confusion about time, place, or familiar people.
  • Impaired Judgment: Difficulty making decisions or solving problems.
  • Changes in Mood or Behavior: Depression, anxiety, paranoia, or aggression.
  • Loss of Interest in Activities: Withdrawal from social interactions or hobbies.
  • Difficulty with Coordination: Problems with balance, walking, or motor skills.
  • Hallucinations or Delusions: Seeing, hearing, or believing things that aren't real.

Diagnosis

Healthcare professionals diagnose dementia through a series of assessments and tests:

  • Medical History and Symptom Assessment: Discussing the onset, duration, and impact of cognitive changes, along with any relevant medical or family history.
  • Physical and Neurological Examination: Evaluating reflexes, sensory function, and movement.
  • Cognitive and Neuropsychological Testing: Using tests like the Mini-Mental State Examination (MMSE) to assess memory, language, and problem-solving skills.
  • Laboratory Tests: Blood tests to rule out vitamin deficiencies, thyroid problems, or infections that may cause similar symptoms.
  • Brain Imaging:
    • Magnetic Resonance Imaging (MRI) or Computed Tomography (CT) Scan: To detect brain abnormalities such as tumors, strokes, or atrophy.
    • Positron Emission Tomography (PET) Scan: To detect patterns of brain activity and identify specific types of dementia.
  • Psychiatric Evaluation: To assess for depression, anxiety, or other conditions that may contribute to cognitive symptoms.
