  Involuntary movements (ataxia, myoclonus or spastic quadriparesis) occur. Myoclonus may be severe and refractory to medications. Visual loss occurs but is less obvious for the same reason as in CLN1. ERG is effective to evaluate visual acuity. [omicsonline.org]

• Mental Deterioration

  The typical early signs are loss of muscle coordination (ataxia) and seizures along with progressive mental deterioration. This form progresses rapidly and ends in death between ages 8 and 12. [brainfoundation.org.au]

  Electroencephalogram (EEG) showed bilateral synchronous generalized epileptiform discharges. Electroretinogram (ERG) was absent and visual evoked potential (VEP) was normal. [pediatricneurosciences.com]

Although there currently is no treatment for this condition, making the correct diagnosis is important for appropriate low-vision management, educational planning, and genetic counseling. [ncbi.nlm.nih.gov]

Management and treatment Treatment is supportive only and should consist of palliative care with administration of anticonvulsive drugs; as well as educational, psychological, and psychiatric management. [orpha.net]

Treatment is specific to the symptoms present in the affected individual, but often includes teams of pediatricians, neurologists, eye doctors, physical therapists, and psychiatrists. [diseaseinfosearch.org]

There is no effective treatment for CLN3. A major impediment to the testing of potential therapeutic interventions is the lack of well-defined outcome measures. [clinicaltrials.gov]
