Abstract

Diabetic peripheral neuropathy is one of the most common chronic complications of diabetes mellitus and represents a significant cause of morbidity and reduced quality of life among patients. Progressive damage to peripheral nerves may lead to sensory disturbances, pain syndromes, motor dysfunction, and disability if not recognized at an early stage. Early diagnosis and timely therapeutic intervention are essential for preventing disease progression and reducing neurological complications. Modern neurological assessment methods and electrophysiological studies contribute to more accurate identification of peripheral nerve dysfunction. This study aimed to evaluate the clinical manifestations and diagnostic approaches for diabetic peripheral neuropathy in patients with diabetes mellitus. The findings demonstrated that comprehensive neurological evaluation significantly improves early detection and disease management.

Diabetes mellitus remains a major global health concern and is associated with multiple neurological complications affecting peripheral and central nervous systems. Diabetic peripheral neuropathy develops as a result of metabolic and vascular changes leading to nerve fiber damage. Clinical manifestations vary from mild sensory symptoms to severe motor deficits and neuropathic pain. Delayed diagnosis frequently results in foot ulcers, gait disturbances, infections, and increased risk of amputation. Therefore, early recognition and appropriate management of neuropathic changes are essential for reducing morbidity and improving patient outcomes.

The aim of this study was to investigate clinical manifestations and evaluate modern approaches for early diagnosis of peripheral neuropathy in patients with diabetes mellitus.

The study included 90 patients diagnosed with diabetes mellitus aged between 35 and 70 years. Comprehensive neurological examination was performed, including assessment of sensory function, tendon reflexes, muscle strength, and pain perception. Additional investigations included nerve conduction studies, laboratory analysis, and evaluation of glycemic control parameters. Statistical analysis was conducted to determine relationships between disease duration, metabolic status, and severity of neuropathic changes.

The study demonstrated that numbness, tingling sensation, burning pain, and decreased sensitivity in lower extremities represented the most common clinical manifestations among patients with diabetic peripheral neuropathy. Neurological examination revealed reduced tendon reflexes and sensory abnormalities in a considerable number of patients. Electrophysiological studies identified early nerve conduction changes even in patients with minimal clinical symptoms. Poor glycemic control and longer disease duration were associated with increased severity of neuropathic complications.

Early diagnosis of diabetic peripheral neuropathy is crucial for preventing disease progression and reducing disability. Comprehensive neurological assessment combined with electrophysiological evaluation improves diagnostic accuracy and allows timely intervention. Effective management of diabetes and regular neurological monitoring may significantly improve long-term patient outcomes.
