Yes, a GP can make an initial diagnosis of dementia by conducting memory/thinking tests, physical exams, and ordering blood work, but often refers to specialists (neurologists, geriatricians) for more complex or definitive confirmation, especially if symptoms are atypical or mild, as dementia diagnosis requires ruling out other causes and detailed investigation.
Only a medical professional who has your test results can diagnose you. This usually means your GP or a specialist, often working together.
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).
Delirium would be unlikely as there is a long history and no obvious acute medical problems. He does not need a scan and definitely has dementia – GP can make this diagnosis. A blood screen, physical examination and urine dipstick may be helpful if feasible and not distressing to the patient.
Early signs of vascular dementia can include mild:
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.
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.
Brain Boosts | Tips to Help Improve Your Memory
A new study suggests that personality traits like neuroticism and conscientiousness may increase dementia risk. Psychological factors appear to affect dementia likelihood though not underlying brain neuropathology. Protective traits, particularly conscientiousness, seem to grow stronger with age against dementia.
A primary care physician cannot diagnose you with dementia, but he or she can help determine if your symptoms could be dementia-related or something else, such as a mood disorder like depression, or if a medication could be causing these behaviors.
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.
Common changes in behaviour
Physicians use diagnostic tools combined with medical history and other information, including neurological exams, cognitive and functional assessments, brain imaging (MRI, CT, PET) and cerebrospinal fluid or blood tests to make an accurate diagnosis.
One of these might be a brain scan, such as a CT scan, or an MRI scan. They may also do further, more detailed memory tests. If the specialist is still not certain about the diagnosis, you may need to have further, more complex tests. But most cases of dementia can be diagnosed after these assessments.
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.
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.
Whereas a separate study of 13,984 adults over age 65 revealed that those who had social support such as friends, family and community groups were 46% less likely to develop dementia than those more isolated.
A recent meta-analysis revealed that higher neuroticism and lower conscientiousness are consistent predictors of higher dementia risk, across dementia types, including Alzheimer's disease (AD), dementia assessment methods, follow-up lengths, and countries (Aschwanden et al., 2021).
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 term pseudodementia refers generically to treatable disorders that mimic dementia. The most common is depression. Depression and dementia can both lead to reduced motivation, impaired concentration, and mental slowing. Consequently, both diseases can lead to widespread cognitive and memory dysfunctions.
“The most common manifestation of B12 deficiency is fatigue.” That fatigue and related symptoms can be confused with symptoms of depression and dementia, he says. People with vitamin B12 deficiency may act forgetful and confused, and struggle with concentrating and accomplishing tasks, Kaiser says.

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.
Common early symptoms of dementia
memory loss. difficulty concentrating. finding it hard to carry out familiar daily tasks, such as getting confused over the correct change when shopping. struggling to follow a conversation or find the right word.
