617 Possible Causes for Absent Deep Tendon Reflex

  • Friedreich Ataxia

    Lower motor neuron lesion: absent deep tendon reflexes. Pyramidal: extensor plantar responses, and distal weakness are commonly found.[]

  • Hypermagnesemia

    deep tendon reflexes) Withhold foods high in magnesium, such as: Remember: “ A lways G et P lenty O f F oods C ontaining L arge N umbers o f M agnesium” Avocado Green leafy[] deep tendon reflexes Low heart rate Dizziness Particularly high levels of magnesium in the blood can lead to heart problems, difficulty breathing, and shock.[] Clinical features generally include nausea, vomiting, muscle weakness, lowered blood pressure, bradycardia, and reduced or absent deep tendon reflexes.[]

  • Spinal Muscular Atrophy

    He has tongue fasciculations and absent deep tendon reflexes. Serum creatine phosphokinase and aldolase levels are normal.[] Other symptoms may include: Decreased or absent deep tendon reflexes, such as the relfex that occurs when you tap on your knee.[] Deep tendon reflexes are absent. Dysphagia may be present. Most children are confined to a wheelchair by age 2 to 3 yr.[]

  • Hyperkalemia

    deep tendon reflexes Diagnosis Suspect hyperkalemia in ALL patients with renal impairment, especially end-stage renal disease (ESRD) Serum potassium Can be artificially elevated[] deep tendon reflexes When hyperkalemia is discovered, investigate potential pathophysiologic mechanisms.[] Deep tendon reflexes may be depressed or absent, though cranial nerves, diaphragm function, and sensation are typically normal.[]

  • Adult Spinal Muscular Atrophy

    deep tendon reflexes Respiratory failure Variable cranial nerve involvement: opthalmoplegia, facial diplegia Additional Specific SMA1Clinical Features [ edit ] Lack of motor[] deep tendon reflexes Severe bulbar palsy Respiratory failure Atrophy and fasciculations in the tongue Weak cry and cough Inability to swallow difficulty feeding, drooling[] Deep tendon reflexes are absent. Dysphagia may be present. Most children are confined to a wheelchair by age 2 to 3 yr.[]

  • Abetalipoproteinemia

    However, deep-tendon reflexes remained absent and plantar reflexes were still upgoing.[] Neurologic examination may reveal diminished or absent deep tendon reflexes and, less frequently, deficits in proprioception and ataxia.[] Neurological examination revealed mild dysarthria, reduced muscle bulk, bilateral proximal muscle weakness, absent deep-tendon reflexes, upgoing plantar reflexes, reduced[]

  • Lambert Eaton Myasthenic Syndrome

    Debilitating muscle weakness, which is the main clinical manifestation of patients suffering from LEMS, is accompanied by reduced or absent deep tendon reflexes, and by various[] LEMS is characterized by depressed or absent deep tendon reflexes which helps to distinguish it from the myopathies and myositis diseases in which deep tendon reflexes are[] Deep tendon reflexes are usually decreased or absent.[]

  • Spinal Muscular Atrophy Type 1

    Deep tendon reflexes are absent. Respiratory failure is common. Mild contractures (of the knees and, more rarely, of the elbows), and scoliosis may be present.[] As the disease progresses, autonomic dysfunction and tongue twitching develop, and deep tendon reflexes are absent.[] Absent or markedly decreased deep tendon reflexes (eg, knee-jerk reflex). Involuntary tongue movements. Hand tremors.[]

  • Familial Periodic Paralysis

    To differentiate it from Guillian Barre syndrome, deep tendon reflexes are normal and 7th cranial nerve is spared.[] (Citation Required) - During an attack reflexes may be decreased or absent.[]

  • Brachial Plexus Neuropathy

    Tone and power were normal throughout, lower limb deep tendon reflexes were absent and plantars were downgoing.[]
