Acute MS treatment
steroids
clinical presentation of MS
- extraocular movement pain
- optic disc swelling
- progressive vision loss
Abnormal LP in MS
- oligoclonal banding
- high IgG/albumin ration

more efficacious: high dose interferon (rebif) and low dose interferon ( avonex)
Rebif
Glatiramer same efficacy as

- Methylphenidates
- Amphatimine
Secondary progressive MS
sustained build up of disability, independent of any relapses
3 types of astrocytomas
- pilocytic
- anaplastic
- glioblastoma
Rosenthal fibers
Pilocytic Astrocytoma
higher grade astrocytomas that have more cells than normal,
evidence of mitoses, and abnormal appearing nuclei
Anaplastic astrocytoma
microscopic features of Glioblastoma
