Main Symptoms of Basilar Artery Stenosis

Basilar artery stenosis means the main brain-stem highway is slowly clogging. Trouble often comes in short waves before a bigger hit. The first red flag is sudden bilateral weakness—both legs or all four limbs feel heavy, rubbery, or give out for seconds to minutes. Vision can dip in both eyes at once, like a curtain falling, or merge into double sight. Some people describe “gray fuzz” that clears when they sit still. Dizziness flashes on with head turns or standing up fast. The room doesn’t spin, but you sway as if on a boat and grab walls to stay upright.... Learn more

Main Symptoms of Prolactinoma

A prolactinoma is a small, benign pituitary tumor that over-produces the hormone prolactin. Because prolactin touches many body systems, the signs can be subtle at first and easy to blame on stress or aging. In women of child-bearing age, periods often lighten or stop altogether. Breast milk may leak even though there is no pregnancy or nursing; some notice a few drops on a bra or during a shower. Fertility drops. Couples can try for months without success, and libido often fades—interest in sex feels like a switch that will not turn on. In men, the first tip-off is usually... Learn more

Main Symptoms of Sciatic Nerve Injury

The sciatic nerve starts in the lower back and runs down each leg. When it is bruised, stretched, or cut, the leg sends clear distress signals. The hallmark is a sharp, shooting pain that begins in the buttock and travels down the back of the thigh. Coughing, sneezing, or sitting on a hard chair can trigger an electric jolt. Numbness or tingling follows the same path. The calf or sole may feel “asleep,” making it hard to sense the brake pedal while driving. Muscle weakness shows up next. The foot may slap when you walk, or you might struggle to... Learn more

Main Symptoms of Peripheral Nerve Injury

When a peripheral nerve is bruised, stretched, or cut, the area it serves quickly lets you know. The first hint is often a lightning pain that shoots along the arm or leg at the moment of injury. Later, a deep burn or constant ache may replace it. Numbness or tingling sets in next. It can feel like the limb “fell asleep,” except the pins-and-needles stay. Hot pans or sharp objects might go unnoticed, leading to accidental burns or cuts. Muscle weakness shows up fast. You may drop coffee cups, struggle to lift the foot while walking, or find buttons impossible... Learn more

Main Symptoms of Communicating Hydrocephalus

In communicating hydrocephalus, the fluid pathways are open, but the brain still can’t drain properly. Pressure builds slowly, so signs often creep in over weeks or months. The first clue is a gait that feels “stuck.” Each step is short, shuffling, and glued to the floor; turning around takes several small pivots instead of one smooth move. Urge incontinence follows. You feel fine, then suddenly must reach a bathroom within seconds. At night, the trip may come too late. Thinking turns murky. Short-term memory slips—why you opened the fridge, where the car keys live. Conversations pause while you hunt for... Learn more
