Any mental disorder test should be accompanied by a physical exam. Since the psychiatric profession admits there is no mental disorder test to determine which of their many labeled mental diseases a person may have, it is important to look elsewhere for a cause.
For example, in determining obsessive compulsive disorder in a child, the mental disorder test has been a miserable failure. There is, in fact, a physical cause behind many cases of OCD. Pediatric autoimmune neuropsychiatric disorders, shortened to PANDAS is caused by streptococcus bacteria.
Children who were infected by certain bacteria such as influenza, varicella (chickenpox), and streptococcal bacteria (strep throat and scarlet fever) sometimes developed a sudden change in personality, sometimes overnight.
Some of the symptoms of this infection are:

• Anxiety attacks
• Extreme mood swings
• Hypersensitivity to light or sound
• visual perceptions being distorted
• Sometimes visual or auditory hallucinations
• Immature behavior, such as “baby talk”
• Hyperactivity
• Attention difficulty
• Trouble with math, reading and other subjects in school
• Changes in handwriting

Since PANDAS is a diagnosable condition, it should be checked for in any case of childhood onset obsessive compulsive disorder, ADHD, ADD, separation anxiety and any other distressful mental symptom.
Putting a child on psychiatric medication which only masks these symptoms is at best ignorant and at worse a specialized form of child abuse. However, even when the physical cause of the child’s mental distress is recognized and diagnosed as PANDAS, this is often the “treatment” given by those in the psychiatric profession.
 
Since the cause of many childhood mental disorders had been discovered, one might expect that a physical treatment be researched and developed. But this is not the case, at least within the psychiatric profession. Instead, the “one size fits all” treatment is SSRI drugs, where potential side effects are as uncomfortable as and even more dangerous than the condition it is meant to cure.
However, there are reports of antibiotic cures, especially when the diagnosis of PANDAS is within the 30 day window of the onset of symptoms. A research of these treatments is available on the internet, and gives parents not just a choice but a hope of real help for their afflicted child.
Some parental observations of PANDAS symptoms in their child are enlightening, and cover some specific behavior that may occur:

• Hand washing that becomes obsessive because of a fear of germs, chemicals or of having sticky hands
• Having an obsession about making sure all urine or fecal matter is out, leading to compulsive wiping
• No longer able to make simple decisions for fear of it being wrong
• Fear of chocking on food; asking that it be cut up in small pieces

The opinion of the psychiatric and pharmaceutical industries that every non-optimum situation is based on a need for a psychotropic drug is absurd and dangerous.
The care of our children and grandchildren does not belong in the hands of those with vested interests. If mental disorder tests became physical disorder evaluations and treatment involved nutrition and non-psychiatric pharmaceuticals, our children would have a chance to grow up happy and self-determined.
