Abstract

Objective: To study the frequency and characteristics of neurological disorders in patients with various hematological malignancies. Materials and Methods: A prospective study was conducted involving 111 patients with hematological malignancies: acute lymphoblastic leukemia (ALL, n=64), acute myeloid leukemia (AML, n=28), and lymphoma (n=19). Cognitive impairment, attention deficit, headache, peripheral neuropathy, movement coordination disorders, and autonomic dystonia were assessed. Results: Cognitive impairment was significantly more common in patients with ALL (63.5±6.2%) compared to AML (57.1±8.6%) and lymphoma (38.5±14.6%) (p<0.001). Other neurological manifestations did not demonstrate statistically significant differences between the groups (p>0.05). Conclusion: Patients with ALL have the highest risk of developing cognitive impairment, which requires special consideration when planning therapeutic and rehabilitation measures.
