The Board has determined that the veteran's current peripheral neuropathy of the feet and onychomycosis are related to his service, specifically cold injury exposure during active duty. The condition of peripheral neuropathy is granted as secondary to a cold injury sustained in service.

The Veteran's service connection claims for peripheral neuropathy of the hands and feet are being remanded due to new evidence received since the last denial, which suggests a possible link between early-onset neuropathy and his Vietnam-era service. The VA will conduct further examinations and obtain additional records to determine if there is a relationship with exposure to herbicide agents.

The Board denied service connection for traumatic brain injury (TBI) due to the lack of evidence showing a current disability and no nexus between the Veteran's in-service fall and his current symptoms.,Service connection was also denied for onychomycosis of the feet as there is no medical evidence linking the condition to active service. The Board found that the Veteran did not have onychomycosis until 1983, which predates his military service.,The claim for a cardiac disorder was denied because there was insufficient evidence to support a current disability and the Veteran's symptoms were deemed musculoskeletal in nature.

The Board denied the Veteran's claim for service connection for a bilateral foot disorder, including residuals of frostbite and peripheral neuropathy, finding that there was no evidence linking these conditions to his military service.

The Veteran's peripheral neuropathy of the feet has been granted service connection. For PTSD with depressive disorder, a rating in excess of 50 percent prior to September 8, 2011, and 70 percent thereafter is denied.
