Understanding Dementia. What it does to the brain and the body (and how to support brain health)
Dementia isn’t a single disease, it’s a term used to describe a group of symptoms that affect thinking, memory, behaviour and the ability to perform everyday activities. Conditions like Alzheimer’s disease, vascular dementia, and Lewy body dementia all fall under the dementia umbrella. These conditions tend to get worse over time.
Effects beyond the brain
Though dementia starts in the brain, its impact ripples through the body:
- Movement and balance problems: Some types (e.g., Lewy body dementia) affect motor control.
- Changes in mood and behaviour: Anxiety, depression, irritability and apathy are common.
- Sleep disturbances: Many people with dementia experience fragmented sleep or restless nights.
- Difficulty swallowing or eating: In later stages, this can affect nutrition and general health.
While currently there’s no cure for dementia, many strategies help people live better for longer. These include mental and physical activity such as exercise and cognitive engagement (e.g., puzzles, newskills) support brain health and may delay symptom onset. Healthy lifestyle, including a balanced diet, quality sleep, and social connection all contribute to maintaining cognitive function as well.
Chiropractic care and brain health
Benefits of chiropractic care that may support overall health for those with dementia can include:
Reduced neck/back pain - Can improve comfort, mobility, and sleep, all important for quality of life in older adults.
Improved posture - Better posture may support breathing and reduce strain that can contribute to headaches, fatigue and stress.
Nervous system stimulation - Spinal health can influence nervous system signalling and overall bodily balance.
Supporting brain health with everyday tips. Here are lifestyle habits that research supports formaintaining brain health:
- Stay physically active. Even moderate regular exercise improves blood flow to the brain.
- Keep mentally engaged. Learning new skills and staying socially connected helps strengthen neural networks.
- Healthy diet. Nutrient-rich foods (e.g., omega-3s, antioxidants) may benefit brain function.
- Manage cardiovascular risks. High blood pressure, diabetes and cholesterol can increase dementia risk if unmanaged.
