Dementia is a broad term for a group of conditions that affect memory, thinking, and social abilities severely enough to interfere with daily life. Alzheimer’s disease is the most common type, but vascular dementia, Lewy body dementia, and others exist. While dementia is more common in older adults, it is not a normal part of aging.

  • Memory loss that disrupts daily activities
  • Difficulty communicating or finding words
  • Trouble with problem-solving or planning
  • Confusion about time or place
  • Poor judgment or decision-making
  • Personality changes or withdrawal from social activities
  • Medications: Cholinesterase inhibitors and memantine can help slow symptoms in some types of dementia
  • Supportive therapies: Cognitive stimulation therapy, occupational therapy
  • Lifestyle changes: Routine, exercise, nutrition, and structured environments
  • Caregiver support: Education, respite care, and advanced care planning

While there’s no cure for most types of dementia, early diagnosis and supportive care can greatly improve quality of life.
