Cause 8. Smoking – A Persistent Threat to Brain Health
The detriments of smoking have been well documented, particularly in the context of lung health and cancer. However, smoking is also a significant risk factor for vascular dementia. The habit exposes the body to various harmful substances, which can lead to damage in blood vessels throughout the body, including the brain.
Smoking injures blood vessels, leading to a condition known as atherosclerosis, where the arteries become narrowed and hardened due to plaque buildup. This reduces blood flow, depriving brain cells of the vital oxygen and nutrients they need to function correctly. Over time, this can lead to the death of these cells, manifesting as cognitive decline and ultimately progressing to vascular dementia.
Smoking also increases the likelihood of blood clots, heightening the risk of stroke – another significant cause of vascular dementia. It further weakens the body’s ability to recover from such events, exacerbating the damage and cognitive impairment. (8)
