Age-Related Dementia Among Older People

Age-Related Dementia Among Older People

Dementia is a condition common in people of advanced age, and it can present itself in various ways. Dementia is a broad word that describes a loss in cognitive abilities, such as memory, language, and problem-solving, severe enough to interfere with daily activities. In simpler terms, dementia is a decline in cognitive abilities severe enough to interfere with daily activities. Although Alzheimer's disease accounts for around half of all cases of dementia in older adults, there are several others. Dementia comes in many forms, each with its symptoms and causes, which are discussed in this article by home care Edmonton experts.

Alzheimer's disease

Sixty per cent to eighty per cent of all cases of dementia can be attributed to Alzheimer's disease. Memory loss is often the first cognitive function to deteriorate in dementia, followed by language, problem-solving, and judgment difficulties. Behavior, personality, and mood changes are all possible as Alzheimer's disease advances in a patient. Abnormal protein accumulations in the brain cause the condition and progressively impair cognitive ability.

Vascular Dementia

Vascular dementia is the second most common type of dementia, accounting for approximately 10% of all dementia cases. It is caused by a lack of oxygenated blood to the brain; this illness is often the result of a stroke or heart problem. The symptoms of vascular dementia might vary depending on the location of the damage in the brain as well as the severity of the damage. Still, they can include confusion, trouble with decision-making, and problems with language and memory.

Lewy Body Dementia

Dementia with Lewy bodies is brought on by accumulations of aberrant proteins in the brain. It's the third most frequent form of dementia, making up between 5 and 10 per cent of all cases. Lewy Body dementia shares features with both Alzheimer's disease and Parkinson's disease. Therefore, its symptoms may resemble those of both disorders. Visual hallucinations, tremors, and varying degrees of focus and attentiveness are some possible manifestations of these symptoms.

Front-temporal Dementia

The frontal and temporal regions of the brain are affected by the uncommon form of dementia known as front-temporal dementia. Damage to the nerve cells in these locations is the root cause of the condition, which can result in shifts in personality, behaviour, and the ability to communicate verbally. The symptoms of front-temporal dementia might vary depending on the location of the damage in the brain, but they may include impulsivity, problems with language, and changes in social behaviour. Frontotemporal dementia is a form of dementia that affects the frontal and temporal regions of the brain.

Mixed Dementia

When a patient is diagnosed with mixed dementia, the most prevalent types of dementia that coexist are Alzheimer's disease and vascular dementia. Diagnosing this particular form of dementia can be challenging because it shares symptoms with both Alzheimer's disease and Parkinson's disease.

Other Types of Dementia

There are a number of additional forms of dementia, each of which is significantly less frequent but is nonetheless essential to identify. These conditions include dementia brought on by Parkinson's disease, dementia brought on by Huntington's disease, and Creutzfeldt-Jakob disease. The same protein deposits that create Parkinson's disease also cause Parkinson's disease dementia, which can lead to issues with thinking, memory, and movement. Parkinson's disease dementia is caused by the same protein deposits that cause Parkinson's disease. A mutation in the gene responsible for Huntington's disease dementia causes the condition, which can result in changes in personality, temperament, and mobility. Creutzfeldt-Jakob disease is an extremely rare kind of dementia that affects the brain and can cause neurological symptoms and dementia to appear suddenly.


In conclusion, there are several types of dementia that older adults can experience, each with its unique symptoms and causes. It is essential to recognize the signs of dementia early and seek medical attention promptly, as early intervention can help manage symptoms and improve quality of life. Although there is currently no cure for dementia, treatments and interventions can help slow the progression of the disease and improve the overall well-being of individuals with dementia and their caregivers. For this case, you can also hire a caregiver from Edmonton Home Care to help seniors to cope with these symptoms and live their remaining life peacefully.
