Dementia is a broad term for a decline in mental ability severe enough to interfere with daily life. It’s not a specific disease, but rather a group of synptoms that can be caused by various underlying conditions. Alzheimer’s disease is the most common cause of dementia, accounting for 60-80% of cases. Other causes include vascular dementia, Lewy body dementia, and frontotemporal dementia.

It affect mainly elderly people. Locally, according to the Well-being of the Singapore Elderly (WISE) study led by the institute of Mental Health in 2024, one in 11 people aged 60 and above may have dementia. By 2030, over 152.000 people in Singapore are projected to live with dementia.

Symptoms of dementia vary depending on the cause and the individual. Common symptoms include memory loss, difficulty with language, impaired judgement, and changes in mood and behaviour. Dementia progresses thorugh stages, from midlife cognitive impairment to severe dementia, with increasing functional decline over time. Diagnosis typically involves a comperhensive medical evaluation, including cognitive tests, brain imaging, and blood tests.

Early detection of deentia is crusial for managing symptoms and improving quality of life. Recognizing early warning signs and seeking medical attention proptly can allow for timely interventions and support. Regular cognitive assessments and awareness of risk factors can aid in early detection.

Several types of dementia exists, each with distinct characteristics and underlying causes. Alzheimer’s disease is the most prevalent, characterized by the accumulation of amyloid plaques and tau tangles in the brain. Vascular dementia results form reduced blood flow to the brain, oftern due to stroke or other vascular conditions. Lewy body dementia involves abnormal protein deposits in the brain, leading to cognitive and motor symtoms. Frototemporal dementia affects the frontal and temporal lobes, impacting behabiour, language, and personality.

Memory loss that distrupts daily life, challenges in planning or solving problems, difficulty completing familiar tasks, confusion with time or place, trouble understanding visual images and spatial relationships, new problems with words in speaking or writing, misplacing things and losing the ability to retrace steps, decreased or poor judgment, withdrawal from work or social activities, changes in mood and personality, difficulty recognizing familiar people or objects, getting lost in familliar places, repeating questions or statements, and difficulty following conversations.

While there is currently no cure for most types of dementia, various treatments can help manage symptomps and improve quality of life. Medications may be prescribed to address cognitive and behavioural symptomp. Non-pharmacological approaches, such as cognitive training, occupational therapy, and support groups, can also be beneficial. Caregiver support and education are essential components of dementia care.

Ongoing research efforts are focused on understanding the underlying causes of dementia, developing new diagnostic tools, and idenfying potential treatments and preventive strategies. Clinical trials are underway to evaluate novel therapies, including medications and lifestyle interventions, Advances in brain imaging and biomaker research are contributing to earlier and more accurate diagnosis.
