Dementia Explained

What is Dementia?

Dementia is not a single disease but a general term for a decline in cognitive function, affecting memory, thinking, language, and the ability to perform everyday tasks. It primarily affects older adults but is not a normal part of aging. Dementia is caused by damage to brain cells, which affects their ability to communicate.

Dementia Health Signs and Symptoms

• Memory loss, especially short-term
• Difficulty concentrating and problem-solving
• Confusion with time and place
• Struggling to follow conversations or find the right words
• Mood changes, including depression, anxiety, or irritability
• Difficulty completing familiar tasks
• Impaired judgment
• Withdrawal from work or social activities

Types of Dementia

• Alzheimer’s Disease: The most common type, characterized by amyloid plaques and tau tangles in the brain.
• Vascular Dementia: Caused by reduced blood flow to the brain, often due to strokes.
• Lewy Body Dementia: Marked by abnormal protein deposits (Lewy bodies) that affect brain function.
• Frontotemporal Dementia: Involves degeneration in the frontal and temporal lobes, affecting personality, behavior, and language.
• Mixed Dementia: A combination of two or more types of dementia, often Alzheimer’s and vascular dementia.

How to Test for Dementia

To diagnose dementia, health professionals use a variety of methods:

• Cognitive Assessments: Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA)
• Blood Tests: To rule out conditions like vitamin deficiencies or thyroid problems.
• Imaging Tests: MRI or CT scans to detect brain abnormalities or strokes.
• Neurological Exams: Assess balance, reflexes, and coordination.
• Psychiatric Evaluation: To identify mood disorders like depression that can mimic dementia.

What Type of Health Professionals Treat Dementia?

• Neurologists specialize in disorders of the brain and nervous system.
• Geriatricians focus on healthcare for older adults.
• Psychiatrists provide treatment for associated mood disorders.
• Neuropsychologists assess cognitive function and behavior.
• Primary Care Physicians may perform initial screenings and coordinate care.

How to Prepare to See a Health Specialist?

• Make a list of symptoms and their frequency.
• Bring a list of current medications.
• Document any family history of dementia or cognitive decline.
• Write down any lifestyle changes (diet, exercise) or life events (bereavement, trauma).

What Questions to Ask a Doctor?

• What type of dementia do I (or my loved one) have?
• What treatments are available, and how effective are they?
• How can dementia progress, and what symptoms should we expect?
• Are there clinical trials or new treatments available?
• What lifestyle changes should be made to improve symptoms?
• How can I plan for future care?

What Type of Treatments Exist?

• Medications: Cholinesterase inhibitors (e.g., donepezil) and NMDA receptor antagonists (e.g., memantine) can help manage symptoms.
• Therapy: Cognitive stimulation therapy (CST), occupational therapy.
• Lifestyle Interventions: Physical activity, social engagement, and mental exercises.
• Supportive Care: Caregiver support, community resources, and memory care facilities.

How to Monitor Dementia

• Home Devices: Medication reminder apps, wearable fitness trackers to monitor physical activity.
• Health Signs: Track any changes in mood, memory, and day-to-day functioning.
• Regular Checkups: Cognitive tests to assess progression.
• Environmental Monitoring: Safety measures like fall detectors and GPS trackers.

How to Manage Dementia

• Create a structured daily routine.
• Simplify tasks and provide clear instructions.
• Keep environments familiar and safe.
• Engage in cognitive and physical exercises to maintain function.
• Ensure consistent social interaction.

Nutrition Dos and Don’ts

• Dos:
  • Follow a Mediterranean diet rich in fruits, vegetables, fish, and whole grains.
  • Stay hydrated.
  • Include Omega-3 fatty acids and antioxidants.
