10 Possible Causes for Generalized Rhythmic Slowing, Rhythmic Slowing, Spasticity - Hyperreflexia

  • Hyponatremia

    They are primarily central nervous system (CNS) manifestations, such as irritability, restlessness, lethargy, muscular twitching, spasticity and hyperreflexia, all of which[]

  • Hydrocephalus

    , hyperreflexia Changes in vital signs resulting from brainstem compression due to herniation Because the fontanelles of infants are still open, the accumulation of CSF can[] […] percentile growth chart) Tense fontanelle Setting sun sign : persistent downward deviation of the eyes due to increased ICP in infants and young children Lower extremity spasticity[]

  • Familial Infantile Myoclonic Epilepsy

    Conclusions: XMESID is a rare X-linked recessive myoclonic epilepsy with spasticity and intellectual disability in boys. Hyperreflexia is found in carrier women.[] […] parasagittal theta 2.5-3Hz generalized spike or polyspike-wave discharges (myoclonus) interrupted by slow wave paroxysmal bursts (atonia) AEDs of choice: Valproate, levetiracetam[] Next, the arms and legs begin to jerk rapidly and rhythmically, bending and relaxing at the elbows, hips, and knees. After a few minutes, the jerking slows and stops.[]

  • Hyperabduction Syndrome

    (Ex: inhibition of stretch-reflex in the spastic hemiparesis).[] […] techniques Slow reversal and slow reversal with opposition (SR and SRO) SR represents rhythmic concentric contractions of all agonistics and antagonistics from a movement[] Among the techniques we mention: rhythmical initiation, active relaxation-opposition movement, repeated contractions, rhythmical stabilization, slow inversion, slow inversion[]

  • Episodic Ataxia

    […] and spasticity, extracerebellar signs commonly seen with other SCA syndromes.[] EEG may be characterized by intermittent and generalized slow activity, frequently intermingled with spikes.[] EEG changes during the episode consisted of rhythmical slow-wave activity over the right hemisphere (possible right temporal lobe onset), becoming spike and slow-wave complexes[]

  • Extrapyramidal Disorder

    Patients will complain of distal paresthesias and weakness of the extremities followed by spastic paresis and ataxia.[] […] myokymia (Isaac’s syndrome) generalized muscle stiffness and persistent contraction due to underlying continuous muscle fiber activity 66.  Slow 2-3Hz rhythmic alternating[] However, in some cases, a tremor, though rhythmic, is irregular, as occurs when tremor is associated with dystonic disorders.[]

  • Lethal Neonatal Spasticity - Epileptic Encephalopathy

    Spasticity and hyperreflexia are often present but some newborn infants are hypotonic.[] […] parasagittal theta 2.5-3Hz generalized spike or polyspike-wave discharges (myoclonus) interrupted by slow wave paroxysmal bursts (atonia) AEDs of choice: Valproate, levetiracetam[] Diagnosis of SPG is established by the following clinical features 1, 2 : Typical clinical symptoms of spastic gait impairment and neurologic findings of spastic weakness,[]

  • Early Infantile Epileptic Encephalopathy Type 26

    Three obligate female carriers had hyperreflexia and the matriarch developed progressive spastic ataxia at age 49 years.[] slow spike and wave EEG pattern, andfast rhythmic bursts during sleep.The concept of EIEE is, therefore, applied to a group ofdevastating brain disorders that vary in terms[] […] spike-waves during wakefulness and bursts of fast rhythmic activity during sleep A slowness in intellectual growth and associated personality disorders[ 8 ] [ 61 ] The age[]

  • Atypical Juvenile Parkinsonism

    Involvement of the corticospinal tract, with spasticity, hyperreflexia, and extensor toe signs, was common (13 of 52 patients [25 percent]), as was cognitive decline (15 of[] Other effective techniques to promote relaxation include slow rotational movements of the extremities and trunk, rhythmic initiation, diaphragmatic breathing, and meditation[] Unlike Parkinson disease, corticospinal tract lesions cause Paresis (weakness or paralysis), preferentially in distal antigravity muscles Hyperreflexia Extensor plantar responses[]

  • Microcephaly with Spastic Quadriplegia

    Hypsarrhythmia Epileptic encephalopathy Intellectual disability, severe Arrhythmia Cerebellar atrophy Flexion contracture Progressive microcephaly Rare Symptoms - Less than 30% cases Hyperreflexia[] Idiopathic generalized epilepsy Between 4 and 8 years of age, thalamic and prerolandic cortical hyperexcitability creates a thalamic-cortical slow-wave loop whose 3 Hz rhythmicity[] This results in increased muscle tone, hyperreflexia, extensor plantar responses and clonus. Ataxia (15%) cerebellar lesion resulting in uncoordinated movements.[]
