SSDI approval odds for nervous system and sense organs.
In SSA research on 1997–2004 claims, about 52% of nervous system and sense organs claims were allowed at the initial level, and roughly 74%were ultimately allowed once appeals are counted. Here’s how claims like these move through the system — and where they fare best.

SSA research on 1997–2004 applications (Meseguer, Social Security Bulletin 73(2), 2013). Rates vary by primary diagnosis; these are older than the current-year stage rates below and describe the historical record, not any one claim.
Nervous system and sense organs account for 9.6% of all SSDI awards (75,421 awards in the latest SSA annual report) — a measure of how common the condition is among awards, not the chance of approval.

Per-condition allowance rates are from SSA research on 1997–2004 claims (Meseguer, Social Security Bulletin 73(2), 2013). Not legal advice. Figures are SSA historical aggregates — award shares and national allowance rates by stage are current; the per-condition rates are older research. Individual outcomes turn on the medical evidence and the specific record.
