Social Security Disability (SSD) is a federal program that provides financial assistance to people with disabilities who are unable to work due to their medical condition. To be eligible for SSD, a person must have a medical condition that meets the Social Security Administration's (SSA) definition of disability and is expected to last for at least one year or result in death.

Conditions that are considered disabilities by the SSA include, but are not limited to:

Musculoskeletal disorders

Cardiovascular problems

Cancer

Lung diseases

Neurological disorders such as multiple sclerosis, Parkinson's disease, and epilepsy

Mental health conditions such as depression, anxiety, and schizophrenia

Immune system disorders

Blood disorders

Skin disorders

Kidney disease

Digestive disorders

Endocrine disorders

It's important to note that the SSA has a strict definition of disability, and not all conditions are automatically considered disabilities for the purposes of SSD. The SSA considers several factors in determining eligibility, including the individual's ability to perform work-related activities and the severity of the condition.
