Watching TV excessively can increase the risk of dementia. A recent study says that people who watched more than five hours of TV a day had a 44% higher risk of developing dementia. The study’s findings were associated with higher rates of stroke and Parkinson’s diseases as well, with up to three hours of TV per day being found to be the best for brain health. In the study, 407,000 people were analyzed between the ages of 37 and 73, with 40,000 of them having brain scans and none having been diagnosed with a prior brain disorder. During a 13-year follow-up, 5,227 people developed dementia, 6,822 had a stroke and 2,308 were diagnosed with Parkinson’s disease. Those studied watched TV for 2.7 hours a day. For those who watched three to five hours a day, they were associated with a 15% higher risk of developing dementia, compared to those who watched for an hour or less. Participants who watched more than five hours had a 44% higher risk, plus a 12% increased risk of stroke and 28% risk of Parkinson’s. (Dailymail)
