280 Possible Causes for Abnormal Saccades

  • Autosomal Recessive Ataxia Type Beauce

    […] in ocular saccades attention defects impaired verbal working memory and visuospatial skills Normal life expectancy Autosomal recessive ataxias are generally associated with[] Behavioral abnormality Difficulty walking Motor delay Slow saccadic eye movements Cognitive impairment Gaze-evoked nystagmus Unsteady gait Cerebellar vermis atrophy Dysmetria[] […] balance imprecise hand coordination postural or kinetic tremor of extremities or trunk dysarthria dysphasia vertigo diplopia lower extremity tendon reflexes dysmetria minor abnormalities[]

  • Gaucher Disease Type 3

    Abstract Exogenous enzyme replacement therapy achieves satisfactory biomedical correction in Gaucher type 1 disease and may halt or reverse neurological progression in type 3, while it does not appear to influence the outcome in type 2. In view of the therapeutic possibilities, early detection and monitoring of[…][]

  • Infantile Neuroaxonal Dystrophy 1

    Unlike many other diagnostic procedures, EEG, now over 80 years old, and epilepsy monitoring, now over 40 years old, have demonstrated their usefulness and stood the test of time. Although the benefits of these diagnostic procedures are clear, monitoring is currently not available to the majority of patients in[…][]

  • Abnormal Eye Movement

    Suggestions are made with respect to possible abnormalities in subcortical mechanisms involved in saccade generation.[] Abnormal horizontal saccades in the same patient.[] Abstract Ten cases with congenital abnormal eye movements were reported. Eye movement abnormalities were confined to horizontal pursuit, OKN, and visual suppression.[]

  • Distractibility

    BACKGROUND: Abnormally high levels of saccadic distractibility have been demonstrated to occur in patients with schizophrenia.[] This saccadic distractibility has previously been found in patients with lesions of dorsolateral prefrontal cortex, implicating an abnormality of prefrontal cortex.[] The implications of these results for the current neuropathological theories of abnormal saccadic distractibility are discussed.[]

  • Niemann-Pick Disease Type D

    Abnormal saccadic movements have been reported as well. Retinal signs such as a cherry red spot are not common.[]

  • Oromandibular Dystonia

    She had abnormal saccadic eye movements, generalized hypertonia and exaggerated jerks in upper limbs.[]

  • Oculomotor Apraxia

    We report a novel PNKP mutation in two siblings with progressive ataxia, abnormal saccades, sensorimotor neuropathy and dystonia consistent with the AOA type 4 phenotype.[] Video-oculography revealed constant impairments in patients such as cerebellar signs, altered fixation, impaired pursuit, hypometric saccades and abnormal antisaccades.[] Patients may have other neurologic abnormalities, including delayed development.[]

  • Niemann-Pick Disease Type C

    Abnormal saccadic movements have been reported as well. Retinal signs such as a cherry red spot are not common.[] Paradoxically, less severe illness was associated with an abnormally reduced saccadic latency.[] Furthermore, neurological examination usually reveals vertical supranuclear gaze palsy and abnormal saccadic eye movements.[]

  • Progressive Supranuclear Palsy

    (xiii) Impaired saccadic or pursuit movements: the specific recording of abnormal saccadic or smooth pursuit eye movements.[] The most frequent baseline clinical feature was postural reflex disturbance, and the second most frequent was abnormal saccade or pursuit eye movements.[] Supranuclear gaze palsy was present early in the disease in 38%, and pursuit or saccadic eye movements were abnormal in 44% of cases where the examination was recorded completely[]
