Abstract

Background/aim: Thalamus infarctions presented with various clinical findings are considered to be related to classical and variative infarction areas. In our study, we aimed to compare the sequela clinical findings of patients with isolated thalamus infarction according to anatomical areas.

Materials and methods: Seventy patients diagnosed with isolated thalamus infarction in our clinic between 2010 and 2020 were included in the study. The infarction areas of the patients were divided into groups by the radiologist, including the variative areas to the classical areas using magnetic resonance imaging. Neurological examinations were performed and recorded. Sequela clinical findings of the groups were compared.

Results: The mean age of all patients was 64.49 ± 13.75 (range between: 33–81) years, and the female ratio was 52.9% (n: 33). Inferolateral area infarction was detected most commonly. The most common complaints were sensory complaints (48.6%), speech disorders (20%), limb weakness (15.7%). There were no significant association between the neurological examination findings of classical and variative area infarctions of patients whose most common admission complaint is sensory deficits (p < 0.05), and significant signs of cognitive impairment were detected in the anterior area compared to other areas (p < 0.001). It can be considered that cognitive impairment we detected in the anterior area developed due to its associations.

Conclusion: In our study where sequela findings were evaluated, the absence of a significant difference in neurological examination findings can be explained by the decline of many acute clinical findings over time.

Keywords: Thalamus infarction; anterior nucleus; classical areas; cognitive impairment; variative areas.
