These include heart disease, diabetes, stroke, high blood pressure and high cholesterol. Work with your doctor to monitor your heart health and treat any problems that arise. Studies of donated brain tissue provide additional evidence for the heart-head connection. These measures include eating a healthy diet, staying socially active, avoiding tobacco and excess alcohol, and exercising both the body and mind.

The first survivor of Alzheimer's is out there, but we won't get there without you. Why is this happening? Scientists do not know. Epidemiological studies have found an inverse correlation between PD and cigarette smoking, smokeless tobacco use, and exposure to secondhand smoke, hinting that something in tobacco could be protective Li et al.
If this is the case, falling smoking rates could be fueling a rise in PD, some researchers propose. For his part, Rocca mentioned head trauma, infectious agents, or alcohol consumption as possible culprits for the PD surge Jul news ; Dec news. Agricultural pesticide use surged after World War II, meaning more people now consume these substances in their diet, Rocca told Alzforum.
Urban crowding and exposure to pollutants have also increased. Could pollutants and pesticides bump up AD incidence as well? AD has been linked to pesticide exposure Jan news , but evidence is scarce. One bit comes from a Canadian study, which reported a 24 percent rise in dementia in people between the ages of 50 and 64 from — Cerasuolo et al.
Since younger people with dementia typically develop a pure neurodegenerative pathology such as AD or frontotemporal dementia, without other age-related disorders or vascular pathology, this hints that AD could be climbing, Rocca said.
The drop in all-cause dementia seen epidemiologically could be explained simply by better cardiovascular health, Rocca suggested.
Stroke and heart disease have been on the wane for up to 50 years, and Canadian researchers report drops of up to 40 percent in new cases since Jones and Greene, ; Sposato et al. Stroke and vascular disease may account for a significant portion of dementia, Rocca said. Their mean age is 96; one-third each are cognitively healthy, mildly impaired, or have dementia.
