The types of dementia have various causes and often affect different areas of the brain, so symptoms are not the same across all dementias. Most people with dementia will experience one or more common symptoms, such as memory loss, impulsivity, and difficulty communicating. These are the typical warning signs of the four primary types of dementia:
Alzheimer’s disease: Memory loss, mood swings, difficulty naming everyday objects, forgetting familiar people, loss of communication skills, confusion about everyday tasks, wandering away from safe places or becoming lost, personality changes, and disturbing or unusual behaviors9
Vascular dementia: Memory loss, confusion, loss of reading, writing, and communication skills, impulsivity or loss of inhibitions, personality changes, losing items or becoming lost easily, and difficulty following directions, performing typical tasks, or learning new skills10
Frontotemporal dementia: Behavioral changes like impulsivity or inappropriate emotional responses, coordination issues such as shaky hands and loss of balance, and communication difficulties like inability to understand speech3
Lewy body dementia: Loss of reasoning skills, disrupted sleep, hallucinations or delusions, tremors, and changes in visual perception
