The Board denied service connection for a skin disorder and an acquired psychiatric disorder. The Veteran's claim for the acquired psychiatric disorder was denied due to lack of credible supporting evidence corroborating his claimed in-service stressors, while the skin disorder claim is pending as it relates to herbicide exposure.

The Board finds the evidence does not support a finding that the Veteran has an acquired psychiatric disorder related to service, particularly given inconsistencies in his statements and lack of combat service.

The Board has determined that new and relevant evidence has been received to warrant readjudicating the appellant's claim of service connection for the Veteran's cause of death. The case is remanded for further development, including obtaining medical opinions regarding the etiology of the Veteran's death.

The Veteran's claim for an increased rating for thoracolumbar spine degenerative arthritis and DDD was granted effective August 29, 2022. Service connection was established for vitreous syneresis / vitreous floaters of both eyes. The claims for service connection for refractive error of both eyes (myopia and astigmatism), bilateral hearing loss disability, residuals of a traumatic brain injury (TBI), obstructive sleep apnea, and an acquired psychiatric disorder (PTSD) were all denied.

The Board denied the Veteran's eligibility for enrollment in VA's Program of Comprehensive Assistance for Family Caregivers (PCAFC) due to her not requiring personal care services for a minimum of six continuous months based on an inability to perform one or more activities of daily living, a need for supervision or protection, or a need for regular or extensive instruction without which the ability to function in daily life would be seriously impaired.
