Dizziness

 

Patients
use this term to encompass a variety of sensations like
light headedness, faintness, spinning, giddiness, mental
confusion, blurred vision or headache.

  

Dizziness is Classified into four categories.

1 Faintness

2 Vertigo

3 Miscellenous head sensation

4 Gait disturbances

  

1] Faintness

Fainting [Syncope] is a loss of consciousness due to
cerebral ischaemia.

   

2] Vertigo

It is a hallucination of self or environmental movement.
It is a feeling of spinning due to disturbance in
vestibular system.

  

3] Miscelleneous Head Sensations –

These include hyperventilation syndrome, hypoglycemia or
somatic symptoms of a clinical depression. These
patients will have a normal neurological examination, or
vestibular function test.

  

4] Gait Disturbaces

Some individuals with gait disorders complain of
dizziness, despite the absence of vertigo or other
abnormal cephalic sensations. The term
“dizziness” is used to describe disturbed a
mobilty.

e.g: Peripheral neuropathy, Myelopathy, Spasticity,
Parkinsonian rigidity, Cerebellar ataxia.

  

Their may be mild associated light headedness, with
impaired sensations from the feet, or poor vision. This
is more common in elderly persons who complain of
dizziness only during ambulation. This is because a
decreased position sense [secondary to neuropathy or
myelopathy] and poor vision create an over reliance on
the aging vestibular apparatus.
