Qualifying for ODSP is not based on the medical condition per se, rather to qualify you must meet the ODSP a defintion of disability AND have financial need.
The defintion of disability is on the ODSP website, but in summary you must have an impairment or condition that will last a year or more and that results in a substantial restriction in your ability to work, take care of yourself etc. To meet the financial need requirement you must have a very low family income. You would need to contact the ODSP program as the assessment is done on a case by case basis. They can also explain the ODSP requirements… Hope this helps.
