Dizziness is a disability in spatial perception and stability.[1] The term dizziness is not specific:[2] it can mean vertigo, presyncope, disequilibrium,[3] or a non-specific feeling such as being drunk or funny.[4] Dizziness is a common medical complaint, affecting 20-30% of persons.[5]
Dizziness is broken down into 4 main subtypes: vertigo (~25-50%), disequilibrium (less than ~15%), presyncope (less than ~15%) and nonspecific dizziness (~10%).[6]
