Making Diagnosis

Clinical Features:

• Headaches (peristent) → worse in the mornings and when lying down (suggests raised ICP)
• Seizures
• Focal Neurological Deficits → ie. changes in speech, vision and hearing
• Cognitive Deficits

<aside> 💡 Persistent headaches that are worse when lying down are classic of space-occupying brain lesions

Investigations:

• Imaging (CT/MRI) → can see well-circumscribed tumours at the junction of gray and white matter
