  • Vascular Dementia

    Vascular dementia (VaD) is a common dementing illness. There are no pharmacological agents with a regulatory approval for its treatment or prevention. Review of published clinical trial reports indicates that early treatment of hypertension, a risk factor for stroke, reduces VaD risk and slows progression. However,[…][]

  • Encephalitis

    To describe a case of leucine-rich, glioma inactivated 1 antibody-encephalitis presenting with psychosis. Case report. A young man with leucine-rich, glioma inactivated 1-antibody encephalitis initially presented with acute psychotic symptoms, short-term memory loss and faciobrachial dystonic seizures. Magnetic resonance[…][]

  • Rolandic Epilepsy

    Abstract Since the first descriptions of Rolandic Epilepsy or benign epilepsy with centrotemporal spikes (BECTS), typical and atypical forms have been reported. Indeed, classical focal seizures are sometimes associated with various atypical ictal symptoms and cognitive or behavioural disorders. In an effort to define[…][]

  • Periventricular Leukomalacia

    BACKGROUND: Although investigators have implicated hypoxic-ischemia (HI) as a potential cause of periventricular leukomalacia (PVL), the role of clinical risk factors or markers for HI in the development of PVL remains controversial. The aim of this study was to identify perinatal HI-related factors associated with[…][]

  • Benign Adult Familial Myoclonic Epilepsy

    The classic interictal EEG finding is the hypsarrhythmia pattern, which consists of a highvoltage, disorganized background with multifocal spike and sharp waves.[] Alvarez and Lombroso reported hypnagogic paroxysmal spike wave activity (minimal epileptiform features, sharp waves embedded into hyperventilation , or hypnagogic hypersynchrony[] This pattern may first occur during non-rapid eye movement sleep and may disappear during rapid eye movement (active sleep) sleep or the waking state.[]

  • Encephalopathy

    […] and paroxysmal bursts of sharp and slow waves, these drugs increase epileptiform activity in known epileptic patients, clozapine increase bilateral spike waves discharges[] […] delta bursts, that is called as paradoxical arousal response 18. * Background slowing * Increased theta delta activity * Paroxysmal sharp waves * Theta bursts * Delta bursts[] *Seen in Anoxic brain damage, CNS supressant drugs and severe hypothermia *Paradoxical arousal response *A stimulus brings out slower activity with generalized high voltage[]

  • Uremic Encephalopathy

    […] discharges (PLEDS). [37] In hypokalemia, diffuse slow activity can be seen together with paroxysmal delta/theta activity, as well as focal paroxysms of sharp waves and spike-waves[] ., frontal intermittent rhythmic delta activity (FIRDA), or spikes and sharp waves as well as spike-wave discharges in temporal regions. [37] In hyponatremia, EEG detects[] […] diffuse slowing in the theta range, followed by paroxysmal delta activity and FIRDA or periodic delta waves, as well as the occurrence of periodic lateralized epileptiform[]
