Q.) Is OCD a biological problem as well as a psychological one?

Technically speaking, yes, our psychological state depends on the connections, chemicals and electrical firings in our brain. However, there is no conclusive evidence to indicate that there is any difference in the brain of someone with OCD and someone without. However it has been shown that people with OCD use different parts of their brain more frequently. These are worry, fear, etc.

You can become completely OCD free by simply changing the way you think.
