Mild cognitive impairment
Thinking changes that are noticeable but do not, by themselves, take away everyday independence.
Overview
Some people later develop dementia. Others do not. See the MCI diagnosis page.
- Frontal lobe (glioblastoma commonest)
- Temporal lobe
- Corpus callosum (butterfly glioma)
- Lower-grade IDH-mutant glioma
- Cerebellum (medulloblastoma)
- Brainstem and spinal cord (diffuse midline glioma, cord tumours)
- Ventricles and ependymal lining (ependymoma)
- Sella and pituitary (pituitary tumours, craniopharyngioma)
- Deep periventricular tissue (CNS lymphoma)
- Meninges and convexity (meningioma)
- Grey-white junction (brain metastases)
- Cerebellopontine angle and eighth nerve (vestibular schwannoma)
- Pineal and suprasellar midline (germ cell tumours)
Gliomas infiltrate along white matter and can cross the corpus callosum, medulloblastoma sits in the cerebellum, and CNS lymphoma favours deep periventricular tissue; none spread through lymph nodes.

No conventional lymphatics: gliomas spread along white matter tracts and, rarely, through cerebrospinal fluid; medulloblastoma can seed the spine.
