The appellant withdrew his appeal on all issues prior to the Board's decision.

The Veteran's claim for service connection for ataxia was remanded, and the RO granted service connection for orthostatic hypotension. The Board finds that this satisfied the Veteran’s claim for service connection for ataxia. The issue of SMC based on aid and attendance is now remanded due to new evidence indicating the need for regular aid and assistance.

The Board has remanded the case due to a lack of a VA medical opinion regarding the etiology of the Veteran's esophageal cancer, which contributed to his death. The examiner is required to provide opinions on whether each service-connected disability contributed substantially or materially to death and if it aided in the production of death.

The Veteran's claim for SMC based on the need for regular aid and attendance has been granted due to his service-connected disabilities, which include hypertension with left ventricular hypertrophy and probable old myocardial infarction, depression with cognitive disorder associated with residuals of cerebrovascular accident, prostate cancer with impotence, dermatitis breast and arms, history of hepatitis, and residuals of cerebrovascular accident with right upper extremity hand weakness. The Veteran requires assistance in performing daily activities due to his disabilities.

The Board denied the veteran's claims for increased ratings for his service-connected lumbar myositis, psychoneurosis and conversion hysteria, residuals of shrapnel wounds of the left thigh and pelvis with retained foreign bodies and scars, and residuals of shell fragment wounds of the right thigh and left leg. The veteran was also denied entitlement to a total disability rating based on individual unemployability due to service-connected disabilities.
