Late-stage symptoms
•Severe memory loss, including forgetting close family members
• Loss of ability to communicate
• Difficulty swallowing and walking
• Total dependence on caregivers
Dementia occurs due to damage to brain cells, which disrupts the communication between these cells, or neurons. Some causes include:
•Neurodegenerative diseases (e.g., Alzheimer’s, Parkinson’s)
• Stroke or vascular diseases affecting blood supply to the brain
• Head injuries from accidents or repeated trauma (e.g., in athletes)
• Infections (e.g., HIV, syphilis)
• Nutritional deficiencies (e.g., vitamin B12 deficiency)
• Toxins such as long-term alcohol abuse
It’s worth noting that some conditions can cause dementia-like symptoms but may be reversible with treatment. These include certain infections, thyroid issues, low blood sugar, dehydration, and nutritional deficiencies. Other factors, like interactions between medications, chronic alcohol use, and sleep apnea, can also lead to symptoms that look like dementia but may improve once the underlying issue is treated.
There is no single test for dementia, but early diagnosis is crucial for managing symptoms and planning care. Doctors use several methods, including:
Medical history — Checking for risk factors like family history or past illnesses.
Cognitive tests — Assessing memory, problem-solving, and language skills.
Brain imaging — CT scans, MRI, or PET scans to detect changes in the brain.
Blood tests — Checking for vitamin deficiencies, thyroid problems, or infections.
While some risk factors like age and genetics cannot be changed, you can reduce your risk of dementia by adopting a healthy lifestyle:
Exercise regularly — Helps maintain brain health and blood flow.
Eat a balanced diet — A diet rich in fruits, vegetables, fish and healthy fats.
Keep your brain active — Reading, solving puzzles and learning new skills.
Manage chronic conditions — Control high blood pressure, diabetes and cholesterol.
