The Board has dismissed the claims for service connection for kidney failure, loss of sense of smell, and loss of sense of taste due to the death of the Veteran.

The appeal for service connection for chronic kidney disease was dismissed due to the Veteran not timely filing a Notice of Disagreement within one year of the rating decision.

The Board granted service connection for PTSD and an initial 20 percent rating for dry eye syndrome with pinguecula, while denying service connection for other psychiatric disorders, bilateral hearing loss, tinnitus, and multiple musculoskeletal conditions. Some claims were remanded for further development.

The Board remands the issue of entitlement to service connection for the Veteran's cause of death, for purposes of entitlement to dependency and indemnity compensation (DIC), as further development is necessary.

The Board granted an effective date of April 28, 2015 for the awards of service connection for various conditions including Parkinson's disease with weakness, tremor, and bradykinesia of the left upper extremity; right upper extremity weakness with tremor and bradykinesia (major); depressive disorder with sleep impairment; right lower extremity weakness with bradykinesia, muscle rigidity, and balance impairment; left lower extremity balance impairment with muscle rigidity; speech changes, right CN-10; speech changes, left CN-10; stooped posture, right CN-11; stooped posture, left CN-11; erectile dysfunction; constipation; loss of sense of smell; and right automatic movements, CN-7; left automatic movements, CN-7.
