* [[Frontal lobe]]: Tumours may contribute to poor reasoning, inappropriate social behavior, personality changes, poor planning, lower inhibition, and decreased production of speech ([[Broca's area]]).<ref name=":22" />
* [[Temporal lobe]]: Tumours in this lobe may contribute to poor memory, loss of hearing, and difficulty in language comprehension ([[Wernicke's area]] is located in this lobe).<ref name=":1" />
* [[Parietal lobe]]: Tumours here may result in poor interpretation of languages, difficulty with speaking, writing, drawing, naming, and recognizing, and poor spatial and visual perception.<ref>{{Cite web|url=https://mayfieldclinic.com/pe-braintumor.htm|title=Brain Tumors: an introduction| vauthors = Warnick R |date=August 2018|website=Mayfield Brain and Spine Clinic}}</ref>

* [[Brainstem|Brain stem]]: Tumours on the brainstem can cause seizures, endocrine problems, respiratory changes, visual changes, headaches and partial paralysis.<ref name=":3" />
* [[Leptomeninges]]: Tumours that spread to the leptomeninges, the lining of the brain, may cause [[cranial nerve palsies]] such as [[facial paralysis]], abnormalities of eye movement, abnormalities of facial sensation or [[dysphagia|swallowing difficulty]], depending on which cranial nerves are involved.<ref name="Schaff 2023">{{cite journal |last1=Schaff |first1=Lauren R. |last2=Mellinghoff |first2=Ingo K. |title=Glioblastoma and Other Primary Brain Malignancies in Adults: A Review |journal=JAMA |date=21 February 2023 |volume=329 |issue=7 |pages=574–587 |doi=10.1001/jama.2023.0023|pmid=36809318 |pmc=11445779 }}</ref>
