Many people affected by dementia are concerned that they may inherit or pass on dementia. The majority of dementia is not inherited by children and grandchildren. In rarer types of dementia there may be a strong genetic link, but these are only a tiny proportion of overall cases of dementia.
Family history by the numbers
Studies of family history say that if you have a close relative who has been diagnosed with Alzheimer's disease—the most common form of dementia in older adults—your risk increases by about 30%. This is a relative risk increase, meaning a 30% hike in your existing risk.
Age. The biggest risk factor for dementia is ageing. This means as a person gets older, their risk of developing dementia increases a lot. For people aged between 65 and 69, around 2 in every 100 people have dementia.
For most people with Alzheimer's — those who have the late-onset variety — symptoms first appear in their mid-60s or later. When the disease develops before age 65, it's considered early-onset Alzheimer's, which can begin as early as a person's 30s, although this is rare.

Administration: The examiner reads a list of 5 words at a rate of one per second, giving the following instructions: “This is a memory test. I am going to read a list of words that you will have to remember now and later on. Listen carefully. When I am through, tell me as many words as you can remember.
Although there is no effective treatment or proven prevention for Alzheimer's and related dementias, in general, leading a healthy lifestyle may help address risk factors that have been associated with these diseases. Control high blood pressure.
The Mini-Cog test.
A third test, known as the Mini-Cog, takes 2 to 4 minutes to administer and involves asking patients to recall three words after drawing a picture of a clock. If a patient shows no difficulties recalling the words, it is inferred that he or she does not have dementia.
What are the foods that fight memory loss? Berries, fish, and leafy green vegetables are 3 of the best foods that fight memory loss. There's a mountain of evidence showing they support and protect brain health.
Most cases are diagnosed in people aged 45-65.
Dementia vs. Alzheimer's Disease: What is the Difference? Dementia is a general term for a decline in mental ability severe enough to interfere with daily life, while Alzheimer's is a specific disease. Alzheimer's is the most common cause of dementia.
Doctors also use brain scans to find evidence of other sources of damage, such as tumors or stroke, that may aid in diagnosis. Brain scans used to help diagnose dementia include CT, MRI, and PET scans.
The Self-Administered Gerocognitive Exam, known as SAGE, is a brief, pen-and-paper cognitive assessment tool designed to detect the early signs of cognitive, memory, or thinking impairments. The test evaluates your thinking abilities. This can help your doctors understand how well your brain is functioning.
The clock-drawing test is a quick way to screen for early dementia, including Alzheimer's disease. It involves drawing a clock on a piece of paper with numbers, clock hands, and a specific time. The inability to do so is a strong indication of mental decline.
The main sign of mild cognitive impairment is a slight decline in mental abilities. Examples include: Memory loss: You may forget recent events or repeat the same questions and stories. You may occasionally forget the names of friends and family members or forget appointments or planned events.
It usually affects many members of the same family at every generation, typically in their 30s, 40s or 50s. The faulty gene is passed down directly from a parent who has the disease to their child, it does not skip generations.
Women are disproportionately affected by Alzheimer's disease (AD), comprising approximately two-thirds of all Alzheimer's patients as well as the majority of caregivers for Alzheimer's patients. Women are nearly twice as likely as men to develop Alzheimer's and live longer than men following an AD diagnosis.
If you have a family member with any form of dementia, get screened around age 40. Getting a brain scan can show early signs of a problem, and cognitive testing can set a baseline for future comparisons.
The current evidence indicates that while chronic stress may play a role in the development or progression of dementia, it does not necessarily cause dementia.
It is quite common for a person with dementia, especially in the later stages, to spend a lot of their time sleeping – both during the day and night. This can sometimes be distressing for the person's family and friends, as they may worry that something is wrong.
Some of the more common triggers for dementia like a change in environment, having personal space invaded, or being emotionally overwhelmed may be easier to handle if you mentally practice your response before you react.
