164 Possible Causes for Downbeat Nystagmus, Hydrocephalus

  • Arnold Chiari Malformation

    Abstract Cortical biopsies of 13 patients with clinical diagnosis of congenital hydrocephalus, Arnold-Chiari malformation and hydrocephalus, and postmeningitis hydrocephalus[] The Arnold-Chiari malfomation is typically associated with downbeat nystagmus.[] We report the second case of focal dermal hypoplasia associated with myelomenigocele, Arnold-Chiari malformation and hydrocephalus and the first in a male.[]

  • Pineal Gland Neoplasm

    Obstructive hydrocephalus was present in only five patients (9.4%); three of them showed clinical signs of Parinaud's syndrome.[] […] invasive, endoscopic treatment of hydrocephalus .[] If there is a secondary hydrocephalus which is not relieved, then progressive lethargy and death may ensue.[]

  • Arnold-Chiari Malformation Type I

    In symptomatic patients, it is associated with: spinal diseases - 50% of cases: syringomyelia hydromyelia cranial disorders - 10% of cases: obstructive hydrocephalus Links[] On lateral gaze, jerk nystagmus in the direction of the gaze and downbeat nystagmus were found.[] Patients with atlantoaxial instability, tethered cord, associated myelomeningocele, hydrocephalus, or elevated intracranial pressure were excluded.[]

  • Brain Stem Disorder

    In addition to spina bifida, other conditions sometimes associated with Chiari malformations include: Hydrocephalus.[] Kids with related problems (such as syringomyelia, hydrocephalus, sleep apnea, or scoliosis) may need medical treatment for those conditions.[] Ocular palsies, paralysis of gaze, cerebellar ataxia Tumor Parinaud Dorsal Midbrain Paralysis of upward gaze and accommodation, fixed pupils, retraction nystagmus Pinealoma, hydrocephalus[]

  • Cerebellar Infarction

    CONCLUSION: Occlusive hydrocephalus caused by cerebellar infarction is infrequent.[] Downbeat nystagmus and a right falling tendency were observed. Brain MRI showed multiple acute infarctions in the left cerebellum.[] Perverted head-shaking nystagmus occurred in 23 (23/37, 62%) patients and was mostly downbeat (22/23, 96%).[]

  • Nystagmus

    A 9-month-old girl with hydrocephalus was examined for esotropia, which was reported to have been present since birth.[] Downbeating and rightbeating nystagmus Downbeating nystagmus means that the eyes drift upward, and "beat" or jump downward. Examples are shown above.[] Hydrocephalus , commonly referred to as water on the brain , is the result of swelling in the brain, due to the accumulation of cerebral spinal fluid within the skull.[]

  • Pineal Gland Dysfunction

    WE HAVE BEEN INFORMED OF WHAT SIDE EFFECTS TO LOOK OUT FOR - INCLUDING HYDROCEPHALUS AND PARINAUD SYNDROME.[] A computed tomography (CT) scan can identify the degree of hydrocephalus (pressure that builds up within the cerebrospinal fluid) and whether the tumor is calcified.[] Although most pineal cysts are small, large pineal cysts can cause a variety of symptoms such as: headaches, normal pressure hydrocephalus (increased pressure on the brain[]

  • Central Positional Vertigo

    For those patients without a mass lesion or hydrocephalus, attention should be paid to the venous circulation to rule out venous thrombosis as the cause of increased intracranial[] Downbeat nystagmus is the most common form of central vestibular nystagmus and results from defective vertical gaze holding that allows for a pathologic upward drift of the[] The actual pathophysiology causing the downbeating nystagmus is not well understood at this point, but it is thought that the downbeating nystagmus results from an imbalance[]

  • Arnold-Chiari Malformation Type 2

    Signs and symptoms Clinical features of hydrocephalus are influenced by the patient's age, the cause of the hydrocephalus, the location of the obstruction, its duration, and[] Nystagmus (irregular eye movements; typically, so-called "downbeat nystagmus").[] nystagmus) Central cord symptoms (eg, hand weakness, dissociated sensory loss, cape anesthesia) In infants, signs of brainstem dysfunction predominate: swallowing/feeding[]

  • Congenital Communicating Hydrocephalus

    […] with congenital communicating hydrocephalus.[] nystagmus Impaired convergence and divergence Excessive convergence tone Convergence-retraction nystagmus Skew deviation, often with the higher eye on the side of the lesion[] When hydrocephalus doesn't occur until later in life, it is called acquired hydrocephalus. This topic focuses on hydrocephalus that is present at birth (congenital).[]
