10 Early Warning Signs of Dementia You Shouldn’t Ignore

2. Repetition. Asking a question over and over or telling the same story about a recent event multiple times are common indicators of mild or moderate Alzheimer’s, according to the Cleveland Clinic.

3. Communication problems. Observe if a loved one has trouble joining in conversations or following along with them, stops abruptly in the middle of a thought, or struggles to think of words or the name of objects.

4. Getting lost. People with dementia may have difficulty with visual and spatial abilities. That can manifest itself in problems like getting lost while driving, according to the Mayo Clinic.

5. Personality changes. A loved one who begins acting unusually anxious, confused, fearful or suspicious, or who becomes upset easily and seems depressed is cause for concern.

6. Confusion about time and place. If someone forgets where they are or can’t remember how they got there, that’s a red flag. Another worrisome sign is disorientation about time — for example, routinely forgetting what day of the week it is, says Jason Karlawish, M.D., a neurologist and professor of medicine at the University of Pennsylvania Perelman School of Medicine and codirector of the Penn Memory Center.

7. Misplacing things. Someone with dementia may put things in unusual places and may have difficulty retracing their steps to find misplaced items, the Alzheimer’s Association notes. 

8. Troubling behavior. If your family member seems to have increasingly poor judgment when handling money or neglects grooming and cleanliness, pay attention.

9. Loss of interest, or apathy. Not feeling especially social from time to time is one thing, but a sudden and routine loss of interest in family, friends, work and social events is a warning sign of dementia. A new study published in the Journal of Alzheimer’s Disease found that apathy may even be a sign that someone is progressing from mild cognitive impairment (MCI) — symptoms of memory loss or thinking problems that are not as severe as dementia — to Alzheimer’s disease. People with MCI are at an increased risk of developing dementia.

10. Forgetting old memories. Memory loss that becomes more persistent is often one of the first signs of dementia. 

Where to find help 

When your loved one is displaying troubling symptoms, a trip to a primary care physician is often the first step. But to get a definitive diagnosis, you’ll need to see a specialist such as a neurologist, geriatrician or geriatric psychiatrist.

If you can’t find one, the National Institute on Aging recommends contacting the neurology department of a nearby medical school. Some hospitals also have clinics that focus on dementia.

Specialists will want to know about the patient’s medical history and habits, since modifiable risk factors like smoking and high blood pressure can play a role in dementia risk. So can a family history.

How is dementia diagnosed?

Some of the methods that doctors use to help diagnose dementia:

• Cognitive and neuropsychological tests assess language and math skills, memory, problem-solving and other types of mental functioning.
• Blood tests are relatively new when it comes to diagnosing dementia and, for the most part, are still limited in clinical settings. Doctors can order one to measure levels of beta-amyloid, a hallmark of Alzheimer’s disease.
• Brain scans such as CT, MRI or PET imaging, can spot changes in brain structure and function. These tests also can identify strokes, tumors and other problems that can cause dementia.
• Psychiatric evaluation can determine whether a mental health condition is causing or affecting the symptoms.
• Genetic tests are important, especially if someone is showing symptoms before age 60. The early-onset form of Alzheimer’s is strongly linked to a person’s genes, according to the Mayo Clinic. Talk with a genetic counselor before and after getting tested.​ ​​​
