Mental Illness

According to the WHO, 25% of the world population is suffering from mental illnesses. But only 40% of these cases are diagnosed and treated. One million annual suicides are the result of these undiagnosed or missed cases. Most common causes for these suicides are depression, dementia, anxiety and schizophrenia.
Senior Citizens are susceptible to a variety of mental illnesses. Depression is the most common of these. When organs such as the heart, lungs, thyroid, pituitary and other glands do not function well, mental processes are affected.   
These health issues are characterized by confusion, memory loss and disorientation.  Diseases such as Parkinson's and Huntington's as well as high blood pressure and strokes may cause it.
