  2. The WHO has projected that depression will be 2nd only to CVD as the world’s leading cause of death and disability by 2020 and will be 1 by 2030 ahead of CVD with dementia being 3rd. • Accumulated evidence states that activity protects against depression and anxiety disorders as well as cognitive decline and dementia associated with aging. • In the US the estimated costs of mental disorders are a combined 6.2% of health care expenditures. • In the US dementia and other diseases of the CNS are leading causes of death and mental disorders account for more than 40% of years lost to disability. • Exercise improves brain health through positive neurogenerative (new cells), neurotrophic (cell growth), neuroprotective (cell survival), neuroplastic (density and complexity of synapses), and vascular (better circulation) changes. • A serious mental illness in the US costs about $16,000 in annual lost earnings, a total impact of $193.2 bill to the economy.

  3. Nearly half Americans will meet the criteria for at least one mental health disorder in their life, usually first in childhood or adolescence. • Half of all lifetime cases start by age 14 and ¾ by 24. • Rates of anxiety, mood and substance use disorders in the US differ according to age, sex and race. • Suicide is the 2nd leading cause of death among 25-34 and the 3rd leading cause of death among 15-24 year olds. • The father of American psychology, William James, recognized exercise as being important for decreasing worry and elevating mood at the turn of the 20th century. • Hippocrates prescribed exercise for his patients suffering from depression. • 17th century scholar Robert Burton (1632) noted in The Anatomy of Melancholy, sloth or physical inactivity had been regarded as a cause of depression since antiquity. • Not only are anxiety and mood disorders the most prevalent mental health problems in the US they are also risk factors for cardiovascular morbidity and mortality.
