CHS may present with neurologic dysfunction and should be considered in the differential diagnosis of children and young adults first seen with symptoms of spinocerebellar degeneration or movement disorders. Common physical findings include abnormal gait, clumsiness, seizures, paresthesia, mental retardation, ataxia, parkinsonism, and peripheral neuropathy. In many persons with CHS, neurologic changes appear in the lymphoproliferative lymphomalike phase. Progressive neurologic deterioration is common in patients who survive early childhood. Generally, such patients eventually enter an accelerated phase of the disease with widespread infiltration by lymphocytes and histiocytes, causing rapid enlargement of the liver, the spleen, and the lymph nodes, and with concurrent severe leukopenia and thrombocytopenia, resulting in death from infection or bleeding.
