Visual-spatial agnosis, praxis deficits and hallucinations can be the features of subacute sclerosing panencephalitis (SSPE) in the early period. This study describes a 15-year-old boy with SSPE presenting with visual agnosia, prosopagnosia, simultanagnosia, optic ataxia, and oculomotor apraxia which are compatible with Balint syndrome. MRI revealed(More)
Autophagy is required for the homeostasis of cellular material and is proposed to be involved in many aspects of health. Defects in the autophagy pathway have been observed in neurodegenerative disorders; however, no genetically-inherited pathogenic mutations in any of the core autophagy-related (ATG) genes have been reported in human patients to date. We(More)
BACKGROUND Panthothenate kinase-associated neurodegeneration (PKAN) belongs to a group of hereditary neurodegenerative disorders known as neuroacanthocytosis (NA). This genetically heterogeneous group of diseases is characterized by degeneration of neurons in the basal ganglia and by the presence of deformed red blood cells with thorny protrusions,(More)
We report a case emphasizing the association of epilepsy with psychopathology. The patient was first referred for impulsive and inattentive behavior at the age of 4, and was diagnosed with attention deficit hyperactive disorder. At the age of 7, intermittent daytime episodes characterized with sudden fear and purposeless running, jumping, clapping, and(More)
OBJECTIVES Transcranial direct current stimulation (tDCS) is a non-invasive and safe method tried in drug-resistant epilepsies, in recent years. Our aim was to evaluate the effect of tDCS in patients diagnosed with mesial temporal lobe epilepsy with hippocampal sclerosis (MTLE-HS) which is a well-known drug-resistant focal epilepsy syndrome. PATIENTS AND(More)
Enteroviruses are encountered as the third most common causative agent of encephalitis [1]. Typically, enterovirus encephalitis has a benign course and tends to recover completely [1, 2]. The majority of the patients with enterovirus encephalitis are children and adolescents in whom the disease frequently takes a benign course [1, 2]. It has been suggested(More)
Rasmussen encephalitis is associated with severe seizures that are unresponsive to antiepileptic drugs, as well as immunosuppressants. Transcranial direct current stimulation (t-DCS) is a non-invasive and safe method tried mostly for focal epilepsies with different aetiologies. To date, there is only one published study with two case reports describing the(More)
Tyrosine hydroxylase (TH) deficiency is an inborn error of dopamine biosynthesis and a cause of early parkinsonism. Two clinical phenotypes have been described. Type "B": early onset severe encephalopathy; type "A": later onset, less severe and better response to L-dopa. We aimed to study the expression of several key dopaminergic and gabaergic synaptic(More)
Neuroacanthocytosis (NA) refers to a group of heterogenous, rare genetic disorders, namely chorea acanthocytosis (ChAc), McLeod syndrome (MLS), Huntington's disease-like 2 (HDL2) and pantothenate kinase associated neurodegeneration (PKAN), that mainly affect the basal ganglia and are associated with similar neurological symptoms. PKAN is also assigned to a(More)
