Dementia is not a disease itself but a syndrome. Dementia is an umbrella term for a group of symptoms that affect memory, thinking, behavior, and the ability to conduct daily activities.

Dementia is the loss of cognitive functioning — thinking, remembering, and reasoning — to such an extent that it interferes with a person’s daily life and activities (https://www.nia.nih.gov/). 

Dementia is the result of changes in certain brain regions that cause nerve cells and their connections to stop working properly. Scientists are still investigating how the underlying disease processes in different forms of dementia start and influence each other.

General Symptoms:

• Memory loss interfering with daily life.
• Difficulty with planning, problem-solving, or decision-making
• Language problems (finding words, following conversations, using unusual words)
• Confusion about time/place, acting impulsively.
• Mood, behavior, or personality changes
• Difficulty with coordination or movement (in some types)
• Difficulty with everyday tasks (cooking, managing money, personal care)
• Not caring about others or family feelings
