PROPOSED METHOD FOR ANALYZING COGNITIVE EFFECTS OF CHIARI MALFORMATION TYPE I AND THE PROGRESSION FOLLOWING CEREBRAL TONSIL REDUCTION

Chiari Malformation Type I (CM-I) is a neurological condition characterized by the descent of cerebellar structures through the foramen magnum. This malformation can be associated with cognitive implications, including impaired executive functioning, slowed processing speed, memory deficits, difficulties with attention and concentration, irregularities in emotional processing, and challenges in communication and fluency. Research indicates that cognitive dysfunction is prevalent in CM-I patients, affecting their daily lives. There are two surgical treatments commonly recommended for CM-I: posterior fossa decompression (PFD) and cerebral tonsil reduction (CTR). While both interventions are supported in the literature, studies on their long-term effects and effectiveness remain debated. The purpose of this research is to develop a conceptual framework that proposes a method for analyzing cognition before and after CTR using standardized neuropsychological assessments. This analysis aims to evaluate the treatment’s effectiveness in relation to concomitant effects and overall quality of daily life.
