Symptoms of a mild head concussion may be subtle following an injury or trauma to the head, but ultimately patients experience a feeling of pressure in the head, headaches, confusion, nausea or vomiting, explains the Mayo Clinic. Some patients may experience a temporary loss of consciousness, slurred speech, fatigue, dizziness or ringing in the ears.
Hours or days after an injury causing a mild concussion, individuals may experience sensitivity to light and noise, irritability or personality changes, memory or concentration problems, and sleep disturbances, according to the Mayo Clinic. Some patients may fall into a depression or experience psychological adjustment problems while others develop disorders of smell and taste.
Children with a mild concussion may appear dazed, cry excessively, develop changes in sleep or eating patterns, and have a loss of balance when walking, explains the Mayo Clinic. It is necessary to consult with a physician when head trauma occurs to assess whether or not a concussion exists. Emergency care is needed immediately if a head trauma patient begins to vomit repeatedly, loses consciousness longer than 30 seconds, develops a headache that continually gets worse or begins to stumble due to confusion or disorientation. Slurred speech and seizures are also signs that emergency care is needed following a head trauma.
