Secondary Conditions of Traumatic Brain Injury
Secondary conditionsย are conditions that are caused by another service-connected condition, like a Traumatic Brain Injury (TBI).
All secondary conditions of TBI can be service-connected as long as they are clearly proven to be the direct result of the TBI. This burden of proof can sometimes be difficult, however, so the VA has made a list of 5 conditions that are automatically considered secondary to TBI if they meet the following criteria:

- Parkinsonโs diseaseย andย Parkinsonismย (which is ratedย analogouslyย withย Parkinsonโs disease) qualify as long as they develop any time after aย moderate or severeย TBI.
3. Dementiaย (specificallyย Alzheimerโs disease,ย frontotemporal dementia, andย dementiaย with Lewy bodies) qualifies if it develops within 15 years after aย moderate or severeย TBI.
4. Depressionย qualifies if it develops within 3 years ofย moderate or severeย TBI or within 12 months ofย mildย TBI.
5. Hormone deficienciesย caused by damage to either theย pituitary glandย or the hypothalamus qualify if symptoms develop within 12 months ofย moderate or severeย TBI.
If your secondary condition qualifies to be rated underย TBI, it is rated on theย TBI Rating System.ย
