Which symptom is commonly associated with dry beriberi?

• A. Heart failure
• B. Peripheral neuropathy
• C. Severe ataxia
• D. Visual disturbances

Answer: (B)

Peripheral neuropathy is commonly associated with dry beriberi due to the deficiency of thiamine (vitamin B1). In dry beriberi, the lack of thiamine leads to metabolic disruptions that primarily affect the peripheral nervous system. This deficiency causes damage to the nerve fibers, resulting in symptoms such as tingling, numbness, and pain in the limbs, which are characteristic of peripheral neuropathy. The condition also often presents with muscle weakness and atrophy, further highlighting the impact on the nervous system. In contrast, heart failure, severe ataxia, and visual disturbances are more closely linked to other conditions or forms of thiamine deficiency, such as wet beriberi (associated with cardiovascular symptoms) or Wernicke-Korsakoff syndrome (associated with severe neurological symptoms). Therefore, while thiamine deficiency can manifest in various ways, the hallmark symptom of dry beriberi is specifically the development of peripheral neuropathy.
