A Rare Case of Neuronal Ceroid Lipofuscinosis 5 in A Child: From Initial Attention Deficit Hyperactivity Disorder Symptoms to Severe Neurodegeneration
Abstract
Neuronal ceroid lipofuscinosis (NCL) is a group of rare, inherited neurodegenerative disorders characterized by the accumulation of lipopigments in neuronal cells. Among these, CLN5 lipofuscinosis is generally considered a juvenile-onset variant, presenting with a complex clinical Picture that includes psychiatric, cognitive, and motor impairments. The aim of this report is to describe a rare case of pediatric CLN5 lipofuscinosis initially presenting with psychiatric symptoms, contributing to early diagnostic challenges. We report the case of a boy aged 7;11 (years; months) who initially presented with symptoms of inattention, hyperactivity, and verbosity at the age of 5, which led to an early diagnosis of attention-deficit/hyperactivity disorder (ADHD). Psychiatric assessments and evaluations were conducted in accordance with DSM-5 guidelines to support the diagnosis and monitor the progression of symptoms. As the disease advanced, additional clinical evaluations, including genetic testing, were performed to confirm the diagnosis of CLN5 lipofuscinosis and assess the progression of motor, cognitive, and psychiatric symptoms. The patient, initially diagnosed with ADHD, experienced a rapid progression over approximately one year to severe neurodegenerative symptoms, including loss of ambulation, vision impairment due to retinal atrophy, and cognitive decline. Genetic testing confirmed CLN5 lipofuscinosis, with accompanying psychiatric symptoms such as anxiety. Early psychiatric symptoms in CLN5 lipofuscinosis may be underrecognized, delaying appropriate diagnosis and intervention. This case highlights the importance of a multidisciplinary approach in the evaluation of psychiatric and neurological symptoms in pediatric patients, especially in the context of rare neurodegenerative diseases.
