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[aafp.org]

  • 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[amboss.com] […] 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[amboss.com]

  • 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.[neurology.org] […] parasagittal theta 2.5-3Hz generalized spike or polyspike-wave discharges (myoclonus) interrupted by slow wave paroxysmal bursts (atonia) AEDs of choice: Valproate, levetiracetam[emilytam.com] 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.[dup15q.org]

  • Hyperabduction Syndrome

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

  • Episodic Ataxia

    […] and spasticity, extracerebellar signs commonly seen with other SCA syndromes.[jnnp.bmj.com] EEG may be characterized by intermittent and generalized slow activity, frequently intermingled with spikes.[ncbi.nlm.nih.gov] 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[doi.org]

  • Extrapyramidal Disorder

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

  • Lethal Neonatal Spasticity - Epileptic Encephalopathy

    Spasticity and hyperreflexia are often present but some newborn infants are hypotonic.[disorders.eyes.arizona.edu] […] parasagittal theta 2.5-3Hz generalized spike or polyspike-wave discharges (myoclonus) interrupted by slow wave paroxysmal bursts (atonia) AEDs of choice: Valproate, levetiracetam[emilytam.com] 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,[centogene.com]

  • Early Infantile Epileptic Encephalopathy Type 26

    Three obligate female carriers had hyperreflexia and the matriarch developed progressive spastic ataxia at age 49 years.[bio2rdf.org] 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[docslide.com.br] […] 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[thieme-connect.com]

  • 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[nejm.org] Other effective techniques to promote relaxation include slow rotational movements of the extremities and trunk, rhythmic initiation, diaphragmatic breathing, and meditation[scientiaricerca.com] Unlike Parkinson disease, corticospinal tract lesions cause Paresis (weakness or paralysis), preferentially in distal antigravity muscles Hyperreflexia Extensor plantar responses[merckmanuals.com]

  • Microcephaly with Spastic Quadriplegia

    Hypsarrhythmia Epileptic encephalopathy Intellectual disability, severe Arrhythmia Cerebellar atrophy Flexion contracture Progressive microcephaly Rare Symptoms - Less than 30% cases Hyperreflexia[mendelian.co] 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[ijcpjournal.org] This results in increased muscle tone, hyperreflexia, extensor plantar responses and clonus. Ataxia (15%) cerebellar lesion resulting in uncoordinated movements.[learn.pediatrics.ubc.ca]
