Dizziness is the sensation of imbalance or floating, impending loss of consciousness, and/or confusion. [2] This is different from vertigo which is characterized by the illusion of rotational movement [ 2 ] caused by the “conflict between the signals sent to the brain by balance- and position-sensing systems of the body”.
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 ...

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.
What causes vertigo and dizziness? “Dizziness is generally a more neurological cause or a potential cardiac cause. For example, it could be a blood flow issue or stenosis of a carotid artery ...
Lesions to the cerebellum can cause dyssynergia, dysmetria, dysdiadochokinesia, dysarthria, and ataxia of stance and gait. [3] Dyschronometria can result from autosomal dominant cerebellar ataxia (ADCA). [4] Andreas Vesalius Fabrica, published in 1543, showing the base of the human brain, including optic chiasma, cerebellum, olfactory bulbs, etc.
Dizziness is a common medical complaint, affecting 20–30% of persons. [4] Dizziness is broken down into four main subtypes: vertigo (~25–50%), disequilibrium (less than ~15%), presyncope (less than ~15%), and nonspecific dizziness (~10%). [5] Vertigo is the sensation of spinning or having one's surroundings spin about them. Many people find ...
A neurological disease refers to any ailment of the central nervous system, including abnormalities of the brain, spinal cord and other connecting nerve fibres. [8] Where millions of people are affected by neurological diseases on a worldwide scale, [8] it has been identified that the number of different types of neurological diseases exceeds six hundred, [9] any of which an individual can incur.
The typical brain sample is a surgical specimen, a brain sample obtained during epilepsy surgery. [1] The International League Against Epilepsy (ILAE) defines 3 hippocampal sclerosis (HS) types: predominant neuronal cell loss in subfields CA1 and CA4 (HS ILAE type 1), subfield CA1 (HS ILAE type 2) or subfield CA4 (HS ILAE type 3).
