aivotärähdyksiä

Aivotärähdyksiä is the Finnish term for concussion. A concussion is a mild traumatic brain injury that affects brain function. It is typically caused by a blow to the head or violent shaking of the head and body. The impact causes the brain to move rapidly back and forth inside the skull, leading to temporary damage to brain cells.

Symptoms of a concussion can vary and may not appear immediately. Common signs include headache, confusion, dizziness, nausea, vomiting, blurred vision, and sensitivity to light or sound. Individuals may also experience difficulty concentrating, memory problems, and changes in mood or behavior. Loss of consciousness can occur, but it is not always present.

Diagnosis of a concussion is usually based on a medical history, neurological examination, and assessment of symptoms. Imaging tests like CT scans or MRIs are generally not needed to diagnose a concussion itself, but may be used to rule out more serious injuries.

The primary treatment for a concussion is rest, both physical and cognitive. This means avoiding strenuous activities, sports, and mentally demanding tasks like reading or using electronic devices until symptoms improve. Gradually returning to normal activities is recommended as symptoms subside, under the guidance of a healthcare professional. Most people recover fully from a concussion within a few weeks, but some may experience prolonged symptoms. It is crucial to seek medical attention if a concussion is suspected to ensure proper management and prevent potential complications.
