There is no defined set of conditions for which a veteran might qualify for disability compensation.  Some typical conditions handled in administering claims for benefits under this program include PTSD, traumatic brain injury, neck or back conditions, knee or ankle conditions, shoulder or wrist conditions, tropical diseases (such as malaria), hearing loss or tinnitus, toxic exposure (such as Agent Orange), and exposure to environmental hazards (such as burn pits or contaminated drinking water).  In certain situations, such as exposure to Agent Orange, burn pits or contaminated drinking water, the Department of Veterans Affairs has developed a list of presumptive conditions for which the claims process is more streamlined for a veteran suffering from such a condition.
