  • Dementia

  • Panayiotopoulos Syndrome

    […] parasagittal theta 2.5-3Hz generalized spike or polyspike-wave discharges (myoclonus) interrupted by slow wave paroxysmal bursts (atonia) AEDs of choice: Valproate, levetiracetam[] The seizures included mainly autonomic symptoms such as nausea, vomiting, pallor, mydriasis, urinary and fecal incontinence, and rarely hypersalivation.[] RESULTS: In children with early-onset BECT, the seizures at times manifested with hypersalivation, vomiting, and focal motor seizures, but the vomiting that developed in the[]

  • Rolandic Epilepsy

    Other abnormalities included unilateral rhythmic frontotemporal or parietotemporal SW and brief bursts of generalized spike waves (alone or in association with the above-mentioned[] Hypersalivation is not just frothing: Suddenly my mouth is full of saliva, it runs out like a river and I cannot speak.[] [9] [10] a. unilateral facial sensorimotor symptoms (30% of patients) b. oropharyngolaryngeal manifestations (53% of patients) c. speech arrest (40% of patients), and d. hypersalivation[]

  • Generalized Motor Seizure

    With generalized convulsive seizures, the ictal EEG is often obscured by artifact. Generalized fast rhythmic spikes are seen in the tonic stage.[] […] rhythmic muscle twitching) Bladder or bowel incontinence Tongue bite lacerations Unresponsiveness Confusion Amnesia Aphasia Fatigue Muscular flaccidity and muscle pain Headache Hypersalivation[] Bursts of spikes and after-coming slow waves are synchronous with clonic jerks. A postictal period of irregular slow activity follows. Imaging. Neuroimaging is normal.[]

  • Benign Familial Infantile Epilepsy Type 4

    […] parasagittal theta 2.5-3Hz generalized spike or polyspike-wave discharges (myoclonus) interrupted by slow wave paroxysmal bursts (atonia) AEDs of choice: Valproate, levetiracetam[] Less often, miosis, hypersalivation, and bladder incontinence occur.[] […] with febrile or afebrile GTC seizure Myoclonic-astatic (atonic) seizures – myoclonic jerk followed by loss of tone for 1-4 seconds 50% have absence seizures EEG findings: Rhythmic[]

  • Parkinson's Disease

    Other effective techniques to promote relaxation include slow rotational movements of the extremities and trunk, rhythmic initiation, diaphragmatic breathing, and meditation[] A prodrome of PD is pathophysiology of the gut manifested by GI symptoms such as dyspepsia, hypersalivation from decreased swallowing, constipation, defecatory dysfunction[] Zaljalova , Hypersalivation in Parkinson’s disease: causes and treatment options , Zhurnal nevrologii i psikhiatrii im. S.S. Korsakova , 115 , 10.[]

  • Lennox-Gastaut Syndrome

    Background The EEG background is abnormal in all cases from onset of seizures, with generalized or focal slowing.[] Mood changes, sedation, ataxia, and hypersalivation, well-known complications of other AEDs, were not observed.[] Mood changes, sedation, ataxia, and hypersalivation, well‐known complications of other AEDs, were not observed.[]

  • Early Infantile Epileptic Encephalopathy Type 6

    Generalized seizures were accompanied at the EEG by electrodecremental activity in 16/39 seizures; diffuse rhythmic slowing in 11/39; slow spike-and-wave complexes in 6/39[] Autonomic symptoms are often mild with cyanosis, apnea, hypersalivation, and respiratory obstruction only occur following very prolonged attacks.[] As the seizure progresses to the clonic phase, the fast rhythm is fragmented by rhythmic slow waves.[]

  • Parkinsonian Disorder

    Patients often have one or several of the following signs: Tremor, or rhythmic unintentional movement Rigidity, or stiffness Bradykinesia, or a sense of slowing down in general[] […] muscular tremors at rest (pill-rolling tremor; 4–6 Hz), paucity and slowness of movement (hypokinesia, bradykinesia) and generalized rigidity (cogwheel and lead-pipe rigidity[] PD generally presents slowly, and progresses slowly over years.[]

  • Anti-NMDA Receptor Encephalitis

    slowing or intermittent rhythmic delta activity on EEG, and some subcortical MRI abnormalities).[] […] opisthotonus 3, startle 2 Dysautonomia 32/44 (72%): tachy/brady-cardia 22, hyperhidrosis 12, persistent pyrexia 10, central hypoventilation 7, labile/high blood pressure 6, hypersalivation[] […] lesions), and the later appearance of basal ganglia and brainstem-localised features (movement disorders, fall in level of consciousness, dysautonomia, CSF oligoclonal bands, generalized[]
