33. Early Onset of Alzheimer’s Disease
According to the National Sleep Foundation, Alzheimer’s Disease will affect the quality of sleep that someone has. This is also a “chicken or the egg” sort of scenario, because some researchers believe that poor sleeping habits may contribute to the deterioration of the brain, and it may be one of the culprits for causing the disease in the first place. People with Alzheimer’s are more likely to have insomnia and sleep apnea, which only contributes to them having all of the other issues mentioned on this list.
