clipper's remarks: The difference of brain tumor symptoms when they are in different pars of the brain. Stands to reason when we know that different parts of the brain control different things. Also you need to watch out for personality changes with brain tumors, that is the scariest thing when someone's personality changes.

Frontal lobe tumours - Changes in personality and intellect. Unco-ordinated walking or weakness of one side of the body. Loss of smell, occasional speech difficulties.

Parietal lobe - Difficulty in speaking or understanding words. Problems with writing or reading. Difficulty in co-ordinating certain movements. Difficulty finding your way around. Difficulty with numbers (doing simple calculations)

Occipital lobe - Loss of vision on one side.

Temporal lobe - Fits may cause strange sensations: a feeling of fear or intense familiarity (dé jà vu), strange smells or blackouts. Speech difficulties and memory problems.

Cerebellum - Lack of co-ordination which affects walking and speech (dysarthria), unsteadiness, flickering involuntary movement of the eyes (nystagmus). Vomiting and neck stiffness.

Brain stem - Unsteadiness and an unco-ordinated walk. Facial weakness, a one-sided smile or drooping eyelid. Double vision.

Test optokinetic nystagmus (OKN) by moving a strip with parallel stripes on it in front of the patient's eyes and asking them to watch the stripes go by. Normally, rhythmic eye movements called nystagmus occur consisting of an alternating slow phase with slow pursuit movements in the direction of strip movement, and a rapid phase with quick refixations back to midline.

Elies W.

The contribution of cervical spine disorders to cochleovestibular symptoms was based on the evaluation of patients complaining of dizziness and/or inner ear hearing loss, treated in the ENT Department of Tubingen University between 1977 and 1982. Cervicogenic vertigo was provoked by movements of the cervical spine, but the latter rarely caused tinnitus and never induced hearing loss. The diagnosis between a vascular or proprioceptive nystagmus may be made on the presence of lesions of the cervical spine. These are disorders of the cranio-cervical or the thoraco-cervical region especially and much less often due to osteochondrosis of the vertebrae. The findings of a cervical osteochondrosis has no diagnostic value unless vertigo is provoked by head movements. In cervical vertigo the thoraco-cervical region should be examined to prove a thoracic outlet syndrome. In selected cases operative treatment is possible, eg. transoral resection of the dental process of the axis, resection of the posterior arch of the atlas, myotomy of the anterior scalenus muscle or decompression of the vertebral artery.
