Signs and symptoms of a concussion can appear gradually and may be subtle at first. It may take hours or a couple of days before they appear and they can last for days, weeks, or even months. Moreover, some symptoms may be more easily detected by a witness than by the person experiencing the concussion. Most of the time, concussions are mild and do not cause life-altering symptoms. With that in mind, here are some common symptoms of a concussion: • Blurry vision • Brain fog or confusion • Concentration and memory issues • Dazed appearance • Delayed answers to questions in conversation • Depression or psychological adjustment issues • Dizziness • Drowsiness or fatigue • Forgetfulness, which may occur as asking the same question repeatedly • Headache • Irritability or other personality changes • Light and noise sensitivity • Nausea and vomiting • Partial memory loss surrounding the traumatic event • Sleep disturbances • Smell and taste disturbances • Slurred speech • Tinnitus, or ringing in the ears Young children may experience different symptoms than adults and often depend on their caregivers to identify their concussion symptoms, particularly if they cannot communicate their feelings. Some symptoms they may experience include: • Changes in their eating or sleeping patterns • Crankiness and irritability • Dazed appearance • Decreased balance and unstable walking • Excessive crying • Listlessness or tiring easier than usual • Reduced interest in their favorite toys or activities • Seizures • Vomiting
