204 Possible Causes for Clonus, Hyperreflexia, Muscle Hypotonia

  • Myelopathy

    […] with radicular symptoms - 16% had pure myelopathic symptoms - 23% had a combination of myelopathic and radiculopathy - upper motor neuron findings such as hyper-reflexia, clonus[] Clinical hyperreflexia was tested at the MCP joint, using a six-axis load cell.[] Motor weakness in the extremities Gait difficulties ("spastic gait," hesitant and jerky) Myelopathic or "upper motor neuron" findings such as spasticity, hyperreflexia, clonus[]

  • Tay-Sachs Disease

    […] attentiveness Increased startle response A cherry red spot of the fovea centralis of the macula of the retina can be seen in 90% of cases Hyperreflexia with sustained ankle clonus[] Examination of reflexes shows hyperreflexia.[] At 6 to 10 months limp and floppy muscles (hypotonia). decreased alertness and playfulness. difficulty sitting up or rolling over loss of motor skills. decreased hearing and[]

  • Infantile-Onset Autosomal Recessive Nonprogressive Cerebellar Ataxia

    […] reduction of nerve transmission giving rise to various clinical manifestations such as paresthesias, loss of vibratory sensation, and proprioception.Severe weakness, spasticity, clonus[] […] coordination of movement 0001310 Gait ataxia Inability to coordinate movements when walking 0002066 Generalized hypotonia Decreased muscle tone Low muscle tone [ more ] 0001290 Hyperreflexia[] […] surgery Two most common varieties: Spastic paresis (70%) Combination of spasticity (causes slow clumsy movements; usually accompanied by hyperactive deep tendon reflexes, clonus[]

  • Spastic Paraplegia

    The knee-jerk is excessive and ankle-clonus is easily obtained.[] On neurological examination, he showed hyperreflexia, spasticity, and weakness in the lower extremities and bilateral Babinski reflexes.[] In infancy, children with SPG47 have very low muscle tone ( hypotonia ).[]

  • Pontocerebellar Hypoplasia Type 1B

    Affected children typically develop temporary jitteriness (generalized clonus) in early infancy, abnormal patterns of movement described as chorea or dystonia, and stiffness[] […] abnormality Muscular hypotonia of the trunk Poor head control Absent speech Cognitive delay Seizures Respiratory system abnormality Skeletal system abnormality Growth symptoms Hyperreflexia[] PCH type 1 has the hallmark of severe muscle weakness. The associated hypotonia may start prenatally or after birth.[]

  • De Barsy Moens Diercks Syndrome

    Chromosome 17q12 Deletion Chromosome 5q minus syndrome Chronic Ear Infections Citrullinemia (aka: Citrullinuria) Cleft Lip Cleft Palate Cleft Palate and Cleft Lip Clinodactyly Clonus[] […] examination disclosed a variety of dysmorphic features, including cutis laxa, progeroid aspect, short stature, multiple hyperextensible subluxated joints, muscular hypotonia, and hyperreflexia[] Other features include joint hyperlaxity, bone fragility, muscle hypotonia, hip dislocation, sunken eyes, microcorneas, and failure to thrive.[]

  • Isolated CoQ-Cytochrome C Reductase Deficiency

    […] syndrome Progressive leukoencephalopathy Fatigable weakness of swallowing muscles Diffuse hepatic steatosis Poor suck Hepatic failure Rigidity Drooling Aggressive behavior Clonus[] Encephalopathy can cause delayed development of mental and motor skills (psychomotor delay), movement problems, weak muscle tone (hypotonia), and difficulty with communication[] […] cardiomyopathy and deafness; trna-lys-related cardiomyopathy-hearing loss syndrome Related symptoms: Ataxia Sensorineural hearing impairment Muscle weakness Peripheral neuropathy Hyperreflexia[]

  • Cerebral Palsy with Spastic Diplegia

    During testing we observed clonus only in gastrocnemius and soleus muscles.[] Classification Physiologic Classification Spastic (most common) Velocity-dependent increased muscle tone and hyperreflexia with slow, restricted movement due to simultaneous[] Hypotonia will usually occur before 1 year old. The muscle tone increases with age and progress to Hypertonia.[]

  • Maple Syrup Urine Disease

    Cerebral edema: If neurological signs develop or worsen (vomiting, lethargy, hyperreflexia, clonus), suspect cerebral edema.[] […] rigidity) and hypotonia (muscle limpness) high-pitched cry Signs of intermediate and thiamine-response MSUD include: seizures neurological deficiencies developmental delays[] […] signs of increased intracranial pressure including the following: Papilledema Disorientation, combativeness Depressed level of consciousness Refractory vomiting Extremity hyperreflexia[]

  • Spinocerebellar Ataxia Type 13

    Tendon reflex is active, ankle clonus is positive. Double side pathological sign is positive. Left body pain is decline. Deep feeling is existed.[] : Clinical features Age of onset - 43-56 years Slow progression Gait and limb ataxia Dysarthria Occular dysmetria Slow saccades Decreased vibratory sense below the knees Hyperreflexia[] hypotonia.[]
