Differential Diagnosis for Wide Base Gait, Leg Numbness, Falls, and Instability in a 50-year-old African American

Single Most Likely Diagnosis

  • Peripheral Neuropathy: This condition is a common cause of wide base gait, leg numbness, and instability, especially in diabetic patients or those with a history of alcohol abuse. The patient's age and ethnicity also increase the likelihood of diabetes, making peripheral neuropathy a probable diagnosis.

Other Likely Diagnoses

  • Vitamin B12 Deficiency: A deficiency in vitamin B12 can cause neurological symptoms, including numbness, gait disturbances, and instability. This condition is more common in older adults and can be due to dietary deficiencies or malabsorption.
  • Lumbar Spinal Stenosis: This condition can cause leg numbness, weakness, and gait disturbances, especially in older adults. The patient's symptoms of wide base gait and instability could be related to spinal stenosis, particularly if they have a history of back pain or trauma.
  • Cerebellar Ataxia: Cerebellar ataxia can cause gait disturbances, including a wide base gait, and instability. This condition can be due to various causes, including stroke, tumor, or degenerative diseases.

Do Not Miss Diagnoses

  • Multiple Sclerosis: Although less common, multiple sclerosis (MS) can cause a wide range of neurological symptoms, including numbness, gait disturbances, and instability. MS can be devastating if left untreated, making it a crucial diagnosis not to miss.
  • Spinal Cord Compression: Spinal cord compression can cause rapid progression of neurological symptoms, including numbness, weakness, and gait disturbances. This condition requires prompt medical attention to prevent permanent damage.
  • Brain Tumor: A brain tumor can cause a variety of neurological symptoms, including gait disturbances, numbness, and instability. Although less common, a brain tumor is a potentially life-threatening condition that should not be missed.

Rare Diagnoses

  • Tabes Dorsalis: This rare condition is a late manifestation of syphilis and can cause gait disturbances, numbness, and instability. Although rare, tabes dorsalis should be considered in patients with a history of syphilis or those who are at high risk.
  • Friedreich's Ataxia: This rare genetic disorder can cause progressive gait disturbances, numbness, and instability. Friedreich's ataxia typically presents in younger adults, but it should be considered in patients with a family history of the condition.
  • Subacute Combined Degeneration: This rare condition is caused by vitamin B12 deficiency and can cause gait disturbances, numbness, and instability. Subacute combined degeneration is a medical emergency that requires prompt treatment to prevent permanent damage.
