The Significance Of Mental Illness

Most people are curious about why people actually suffer from mental illness. By taking a step back and examining the science of mental illness you will be able to unlock the mystery behind mental illness and how it manifests itself.

Statistics

Although mental illness affects 1 in every 4 adults, only 36% of people with a mental disorder actually receive treatment. Approximately 1 in every 2 people diagnosed as having a mental disorder may suffer from multiple disorders. Let’s take a look at the various types of mental disorders. Mood disorders, major depressive disorder, dysthymic disorder, bipolar disorder and schizophrenia account for 9.5%, 6.7%, 1.5%, 2.5%, and 1.1% of mental illness cases respectively. About 18.1% of people suffer from anxiety disorders. An accumulation of all mental disorder cases accounts $57.5 billion dollars on an annual basis.

Effects on the Brain

What actually happens in the brain of someone suffering from mental illness? Studies have shown that there is in fact a chemical imbalance which is responsible for the development of many mental disorders. Scientists believe that this chemical imbalance affects the brains ability to transmit messages from one neuron to another neuron therefore affecting the brains ability to function normally.

Chemical Effects on Mental Disorders

What chemicals are linked to mental disorders? Several different chemicals have been associated with mental disorders including acetylcholine, dopamine, serotonin, gaba (gamma-amino butyric acid, norepinephrine, adrenaline and epinephrine. Levels of these chemicals are not properly balanced in people with mental disorders. Too much acetylcholine causes depression and too little causes dementia. Excess amounts of dopamine causes schizophrenia and insufficient amounts causes depression, muscular rigidity and tremor like behaviors such as those present in people with Parkinson’s disease.

Too much serotonin is the major cause of depression and some anxiety disorders, primarily obsessive-compulsive disorder. Inadequate levels of gaba is linked to anxiety and anxiety disorders. An increased amount of norepinephrine is associated with schizophrenia while a scarce amount of norepinephrine is linked to depression. Too much adrenaline causes both anxiety and anxiety disorders while too little epinephrine is associated with depression.
