Nonspecific dizziness
The most nebulous category — wooziness, fog, floating, or feeling “disconnected” — that resists localisation and is often psychological, metabolic, or functional.
When dizziness won't localise
Some patients can't describe a spin, a faint, or unsteadiness — just a vague woozy, foggy, or floating feeling. This “nonspecific dizziness” often comes with anxiety, panic, or low mood, and frequently persists even when all the balance tests are normal.
It's real and disabling — and it often improves with treatment aimed at the underlying anxiety or mood, such as talking therapy.
Nonspecific dizziness covers ill-defined, non-localising symptoms — fogginess, grogginess, floating — characteristically seen in anxiety, panic, and somatoform disorders.1 Hyperventilation is a classic trigger: stress-driven rapid breathing causes respiratory alkalosis, producing light-headedness and paraesthesiae.
Psychogenic dizziness can also follow an acute vestibular insult and evolve into a chronic functional syndrome if anxiety goes unmanaged — the bridge to PPPD.2
Nonspecific dizziness is a diagnosis to hold lightly: exclude organic and metabolic mimics (anaemia, hypoglycaemia, drug effects, arrhythmia) before attributing symptoms to a functional or psychiatric cause. Where hypervigilance and avoidance dominate and tests stay normal, recognise the functional pattern early and steer toward CBT, vestibular rehabilitation, and SSRIs rather than repeated negative testing.3
