Before you can attempt to explain mental illness to family and friends, you must be able to grasp the concept yourself. This doesn’t mean studying medical textbooks and reviewing research papers, but it does require some deciphering.
So, what is a mental illness? Well, it can be any combination of factors that impair normal cognitive, behavioral, or emotional functioning. These factors may be biochemical, psychological, genetic, or social in nature. The difficulty is determining which factors are the root causes and how they are impairing normal functioning.
Every mental illness is different and unique. Disorders can be related to mood, depression, anxiety, personality, substance abuse, addictions, and more. While doctors may be able to diagnose a particular mental illness, they are rarely identical between two people.
