103 Possible Causes for Absent Knee Reflex, Paresthesia, Slow Nerve Conduction Velocities

  • Guillain-Barré Syndrome

    In GBS, deep tendon reflexes in the legs, such as knee jerks, are usually lost. Reflexes may also be absent in the arms.[ninds.nih.gov] CONCLUSIONS A case of a rare variant of GBS is presented with facial diplegia and paresthesia and with unilateral facial palsy.[ncbi.nlm.nih.gov] Nerve conduction analysis will reveal slow nerve conduction velocities due to the damage to the nerve.[emedicinehealth.com]

  • Chronic Inflammatory Demyelinating Polyneuropathy

    Knee and ankle jerk reflexes were absent. No abnormalities involving the cranial nerves were found.[omicsonline.org] The authors present the case of a 65-year-old woman who was admitted for paraparesis and paresthesias in the inferior limbs.[ncbi.nlm.nih.gov] Although the patient noticed little muscle weakness, an electrophysiological study demonstrated slow conduction velocities and prolonged distal latencies, with definite conduction[ncbi.nlm.nih.gov]

  • Charcot Marie Tooth Disease

    Sensory loss is often identified when the doctor tests for deep tendon reflexes, such as the knee jerk, which are reduced or absent in CMT patients.[web.archive.org] Patients also complain of numbness and tingling in their feet and hands, but paresthesias are not as common as in acquired neuropathies.[doi.org] HMSN1 is the most common form of hereditary neuropathy, characterized by severely and uniformly slowed nerve conduction velocities and primary hypertrophic myelin pathology[medlink.com]

  • Diabetic Peripheral Neuropathy

    Ankle reflexes are usually reduced or absent, and knee reflexes may also be reduced in some cases.[clinical.diabetesjournals.org] It typically causes burning pain, paresthesias, and numbness in a stocking-glove pattern that progresses proximally from the feet and hands.[ncbi.nlm.nih.gov] […] of nerve conduction velocities, an indicator of demyelination.[nejm.org]

  • Peripheral Neuropathy

    Ankle reflexes are usually reduced or absent, and knee reflexes may also be reduced in some cases.[clinical.diabetesjournals.org] Chemotherapy-induced peripheral neuropathy is a debilitating side effect of chemotherapy, which manifests as paresthesias, dysesthesias, and numbness in the hands and feet[ncbi.nlm.nih.gov] Nerve conduction studies can distinguish demyelinative neuropathy (slowing of conduction velocity or conduction block) from axonal neuropathy (low-action potential amplitudes[neuropathology-web.org]

  • Diabetic Polyneuropathy

    Ankle reflexes are usually reduced or absent, and knee reflexes may also be reduced in some cases.[clinical.diabetesjournals.org] Its symptoms are paresthesia, dysesthesia and pain.[ncbi.nlm.nih.gov] . [4] Sensorimotor polyneuropathy [ edit ] Longer nerve fibers are affected to a greater degree than shorter ones because nerve conduction velocity is slowed in proportion[en.wikipedia.org]

  • Friedreich Ataxia

    Most people with FA also have reduced or absent leg reflexes, such as the knee-jerk reflex. In a small fraction of people, FA leads to hearing loss or visual impairment.[web.archive.org] She denied any pain, numbness, tingling, difficulty with walking distances or up stairs, or fine motor problems including writing, tieing shoes, brushing teeth or eating.[pediatriceducation.org] Medical problems associated with CMT1 include distal muscle weakness and wasting/atrophy, sensory loss, and slow nerve conduction velocity.[forgottendiseases.org]

  • Alcoholic Neuropathy

    Depending on the level of nerve damage in diabetic and alcoholic neuropathy (polyneuropathy) damage sensitivity (numbness, tingling, burning, and "goose"), pain and muscle[minclinic.ru] Motor conduction velocities and sensory nerve action potential amplitudes were also measured in the ulnar nerves.[ncbi.nlm.nih.gov] Clinical manifestations include variable degrees of weakness; atrophy; paresthesias; pain; loss of reflexes; sensory loss; diaphoresis; and postural hypotension.[icd9data.com]

  • Peroneal Nerve Compression Neuropathy

    Weak hip flexion and loss of extension of the knee will cause difficulty in climbing stairs. Decreased or absent knee jerk reflexes confirm the diagnosis.[academic.oup.com] Paresthesia still were present 18 months after surgery.[anesthesiology.pubs.asahq.org] Slowing of peroneal nerve conduction velocities at the fibula head may or may not be detected.[neupsykey.com]

  • Diabetic Mononeuropathy

    The weakness was associated with reduced or absent lower extremity reflexes, with knee jerks absent bilaterally in 32 patients, for example, and reduced in seven. Dr.[journals.lww.com] In diabetic polyneuropathy, the patients may experience unusual sensations (paresthesias), numbness and pain in their hands and feet.[hopkinsmedicine.org] . [4] Sensorimotor polyneuropathy [ edit ] Longer nerve fibers are affected to a greater degree than shorter ones because nerve conduction velocity is slowed in proportion[en.wikipedia.org]
