This is a common question from concerned parents, yet we don't have a really good answer just how long post- concussive symptoms last in kiddos. Well Matthew Eisenberg and friends at Boston Children's attempted to shine some light on this. They conducted a secondary analysis of a prospective cohort study of patients 11 to 22 (mean of 14) years old presenting to the ED with an acute concussion. Patients with a GCS <13, concomitant traumatic injuries, developmental delay, or intentional trauma were excluded. The main outcome measure was duration of symptoms, assessed by the Rivermead Post-Concussion Symptoms Questionnaire (RPSQ) sion. The main outcome measure was duration of symptoms also assessed by the RPSQ. What they found was of the 235 patients diagnosed with a concussion, headache (85%), fatigue (64%), and dizziness (61%) were the most common physical complaints and taking longer to think (58%), poor concentration (52%), and forgetfulness (42%); emotional symptoms/frustration (28%), irritability (26%), restlessness (25%), and depression (23%) were the most common cognitive symptoms. Median duration of symptoms was 13 days. Physical symptoms seemed to improve gradually, while the cognitive symptoms seemed to get worse over the first 7 days, and then began to gradually improve. At 28 days out, the most common complaints were headache (25%), fatigue (22%), taking longer to think (18%), and poor concentration (17%). At 90 days out, headache was the most common symptom (5%). So what does this study tell us? Kids have a significant burden of disease after concussion (especially the first 14 days), with typical patients experiencing physical effects such as headache immediately after the injury, emotional symptoms later in the recovery period, and cognitive symptoms that may be present throughout.
