The Board denied service connection for beriberi, dysentery, malnutrition, malaria, and anemia as the veteran did not have these conditions during his active duty or for decades thereafter. The Board also found that he was not a prisoner of war.

The Board denied service connection for a vitamin D deficiency and remanded claims for coronary artery disease, status post femoral bypass, chronic kidney disease, and anemia due to a pre-decisional duty to assist error.

The appeal for service connection for fibromyalgia was granted with an effective date of August 14, 2023. The appeals for earlier effective dates and higher ratings were denied.

The appeals for service connection for anemia, left and right foot conditions (swelling bilateral feet), prostate issues, tension headaches and head injury with short term memory loss and blurred vision, and vertigo were dismissed as the Veteran withdrew them. The claims for readjudication of tension headaches and head injury with short term memory loss and blurred vision and vertigo will be considered based on new evidence submitted.

The Board granted an increased disability evaluation of 100 percent for service-connected malaria, finding the evidence to be in approximate equipoise as to whether the Veteran's malaria was active during the appeal period.
