Main Symptoms of Intracranial Hematoma

An intracranial hematoma is a pocket of clotted blood inside the skull. It can grow quickly after a head bump or appear days later when a small vein keeps leaking. As the clot expands it squeezes the brain and raises pressure, producing clear warning signals. The first sign is often a headache that ramps up over minutes to hours. It feels like a steady drum inside the head and is usually worse when lying flat. Nausea and vomiting can follow the headache without any stomach upset. The vomit may come on suddenly and bring brief relief, then return. Thinking becomes... Learn more

Main Symptoms of Intracranial Infection

An intracranial infection means germs have reached the brain or its coverings. The immune system sounds an urgent alarm, and symptoms climb quickly. Fever is usually first. Temperature spikes to 38–40 °C (100–104 °F) and can swing from chills to sweats within an hour. Headache follows fast. It feels like steady pressure or a band tightening around the skull and grows worse when you move your head or bend forward. Neck stiffness appears early. Tilting the chin toward the chest feels like a pulled muscle, and bright light may make the pain spike. Nausea and vomiting hit without stomach upset.... Learn more

Main Symptoms of Increased Intracranial Pressure

Increased intracranial pressure means the fluid and tissue inside the skull are under too much tension. When the brain is squeezed, warning signs show up fast and tend to pile on top of each other. The headline symptom is a steady, pounding headache that feels like your head is over-filled. It is usually worse when you lie flat, cough, or bend forward and may wake you from sleep. Vision blurs next. Lights seem too bright, you see double for a few seconds, or the edges of your sight turn gray. Closing one eye does not clear the blur. Nausea arrives... Learn more

Main Symptoms of Arachnoid Cyst

An arachnoid cyst is a fluid-filled sac sitting between the brain and its thin covering. Most stay silent, but if they grow or press on nearby parts they start to whisper clues. The first clue is a dull headache that feels like pressure from the inside. It may come and go, often worse after bending over or coughing. Nausea can ride along. You feel queasy without fever and might throw up once, then feel fine for days. Vision may blur at the edges. You notice you bump into door frames or miss words on the left side of a page,...

Main Symptoms of Brain Edema

Brain edema is extra fluid packed into brain tissue, pushing the brain against the skull. Pressure climbs fast and shows early signs anyone can spot. The first sign is a squeezing headache that feels like your head is in a vise. It is worst when you lie flat or bend over and may wake you from deep sleep. Vision blurs next. Lights seem too bright, colors wash out, and you see double for a few seconds. Closing one eye does not clear the blur. Nausea hits hard. You feel seasick without moving and may throw up suddenly, often with no... Learn more
