Lysosomal storage disorders characterized by defective heparan sulfate (HS) degradation, such as Mucopolysaccharidosis type IIIA-D (MPS-IIIA-D), result in neurodegeneration and dementia in children. However, dementia is preceded by severe autistic-like behaviours (ALBs), presenting as hyperactivity, stereotypies, social interaction deficits, and sleep disturbances. The absence of experimental studies on ALBs' mechanisms in MPS-III has led clinicians to adopt symptomatic treatments, such as antipsychotics, which are used for non-genetic neuropsychiatric disorders.

Lambert-Eaton myasthenic syndrome (LEMS) is an autoimmune neuromuscular junction disorder characterized by proximal weakness, autonomic dysfunction, and areflexia associated with antibodies against voltage-gated calcium channels (VGCCs). Psychotic symptoms can occur in many autoimmune neurological disorders but they have rarely been observed in myasthenic syndromes. We report the case of a 21-year-old woman with primary autoimmune LEMS due to anti-VGCC antibodies subtype P/Q, who developed psychotic symptoms 3 years after the onset of motor symptoms.
