You should suspect dementia when you notice persistent, disruptive changes in memory (especially recent events), thinking, problem-solving, language, or personality, beyond normal aging, such as getting lost in familiar places, trouble with familiar tasks, poor judgment, or losing interest in hobbies, which significantly impact daily life and independence.
But here's the thing—dementia doesn't just happen to older people. While age is still the biggest risk factor for dementia, people in their 50s and 40s (and even 30s and 20s) can also develop dementia. We call this young onset dementia. Young onset dementia accounts for an estimated 2 to 8% of all dementia cases.
These include:
Alzheimer disease affects memory, thinking, and behavior. There is no known cure, but early diagnosis and treatment can lead to better quality of life. Stay healthy with a good diet and regular exercise. Stay away from alcohol and other substances that may affect memory, thinking, and behavior.
Tips for Living Alone With Early-Stage Dementia
The number one cause of dementia is Alzheimer's disease, responsible for 60-80% of cases, characterized by brain plaques (beta-amyloid protein) and tangles (tau protein) that damage nerve cells, leading to progressive memory and cognitive decline, though vascular dementia from blood vessel damage is also a significant factor.
The Self-Administered Gerocognitive Exam (SAGE) is a brief self-administered cognitive screening instrument used to identify mild cognitive impairment (MCI) from any cause and early dementia.
You Miss Out on Sleep
You do a few things you know you shouldn't -- we all do. But some of those bad habits can take a toll on your brain. For example, lack of sleep may be a cause of dementia, including Alzheimer's disease. It's best to have regular sleeping hours.
People with symptoms of dementia are given tests to check their mental abilities, such as memory or thinking. These tests are known as cognitive assessments, and may be done initially by a GP. There are several different tests. A common one used by GPs is the General Practitioner Assessment of Cognition (GPCOG).
Overall, know that Alzheimer's disease is a specific disease, while dementia is a general term for a group of similar diseases, of which Alzheimer's is one. In other words, every case of Alzheimer's disease is an example of dementia, but not every type of dementia is Alzheimer's.
The "2-finger test" for dementia involves an examiner showing a hand gesture (like interlocking index and middle fingers) and asking the patient to copy it, testing motor skills, visual memory, and coordination, as difficulties can signal early cognitive decline, but it's a screening tool, not a definitive diagnosis, prompting further medical evaluation. Other related tests include finger-tapping and finger-to-nose, looking for hesitation or misjudgment in movement.
In the early stages of dementia, a person's symptoms are often relatively mild and not always easy to notice. Common early-stage symptoms include problems with memory, speed of thought, language or perception.
Although the early signs vary, common early symptoms of dementia include: memory problems, particularly remembering recent events. increasing confusion.
Our results confirm that vitamin D deficiency is associated with a substantially increased risk of all-cause dementia and Alzheimer disease.
Smoking, low physical activity, and a poor diet are all lifestyle and environmental influences that have been linked to rapid dementia decline. Physical activity promotes cardiovascular health, which in turn improves brain function. Those who lead a sedentary lifestyle may experience faster cognitive decline.
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.
Vitamin D supplements are linked to a significant reduction in dementia risk, with a major study showing users had a 40% lower incidence of developing dementia compared to non-users, particularly benefiting older adults, with even greater effects seen in women and those without existing cognitive issues. This reduction highlights Vitamin D's role in brain health, possibly by clearing amyloid plaques associated with Alzheimer's.
Early signs of dementia
In the early stages of dementia, people typically start to experience symptoms that affect their everyday living, including: problems with memory and concentration. difficulties with language and communication, such as finding the right words and following conversations.
They also found that breakfast skippers were more likely to experience cognitive decline and signs of neurodegeneration during the study period. Ultimately, the researchers concluded that “breakfast skipping was linked to an increased risk of long-term cognitive decline and neurodegeneration among older adults.”
The cause of roughly 70% of all dementia cases is Alzheimer's disease, a progressive brain disorder characterized by the buildup of amyloid plaques and tau tangles, leading to memory loss and impaired thinking that interferes with daily life, making it the most common form of dementia.
The 10 warning signs of dementia include memory loss, difficulty with familiar tasks, confusion about time/place, trouble with language, poor judgment, misplacing things, personality changes, loss of initiative, and problems with visual/spatial skills, requiring professional assessment to distinguish from normal aging.

Common changes in behaviour
Blood tests for Alzheimer's disease exist and have been extensively tested in research studies to show that they are accurate in diagnosing Alzheimer's disease. They are also used in distinguishing it from other diseases that cause dementia.
