The symptoms of vestibulocerebellar syndrome vary among patients but are typically a unique combination of ocular abnormalities including nystagmus, poor or absent smooth pursuit (ability of the eyes to follow a moving object), strabismus (misalignment of the eyes), diplopia (double vision), oscillopsia (the sensation that stationary objects in the visual field are oscillating) and abnormal ...
Some experts believe post-concussion symptoms are caused by structural damage to the brain or disruption of neurotransmitter systems, resulting from the impact that caused the concussion. [medical citation needed] Others believe that post-concussion symptoms are related to common psychological factors. Most common symptoms like headache ...
The symptoms include poor balance and difficulty walking. Chronic cough and difficulty swallowing may also be present. Clinical findings include ataxia, sensory neuropathy, and absence of the vestibulo–ocular reflex. The syndrome was initially described in 2004. [1]
The relative risk of post-traumatic seizures increases with the severity of traumatic brain injury. [20] Pain, especially headache, is a common complication following a TBI. [1] Being unconscious and lying still for long periods can cause blood clots to form (deep venous thrombosis), which can cause pulmonary embolism. [21]
A change in the magnitude of the vestibulo-ocular reflex due to vestibular disease can also lead to oscillopsia during rapid head movements. [3] Oscillopsia may also be caused by involuntary eye movements such as nystagmus , or impaired coordination in the visual cortex (especially due to toxins ) and is one of the symptoms of superior canal ...
Problems with balance can occur when there is a disruption in any of the vestibular, visual, or proprioceptive systems. Abnormalities in balance function may indicate a wide range of pathologies from causes like inner ear disorders, low blood pressure, brain tumors, and brain injury including stroke.
The unusual vestibular stimulation also caused motion sickness symptoms: illusions of bodily rotations, dizziness, and nausea. These symptoms subside in a few seconds after assuming an upright posture. [21] After some time, the density of cupula and endolymph equalizes, removing the nystagmus effect.
The most common disorders that result in vertigo are benign paroxysmal positional vertigo (BPPV), Ménière's disease, and vestibular neuritis. [1] [2] Less common causes include stroke, brain tumors, brain injury, multiple sclerosis, migraines, trauma, and uneven pressures between the middle ears.
