Dear Neurotalk,

I'm posting because my mother, who lives abroad, age early 70s, tripped and banged her head against a brick or concrete wall while out walking last year.

Apparently she didn't lose consciousness or go dizzy but a friend who had accompanied her reported that the collision resulted in an audible crack as her head struck the solid surface. She wisely got to the hospital within an hour or two to get herself checked out but no concussion or fracturing was detected.

However during her last visit in England I found her noticeably irritable and I have read elsewhere that aggressiveness is a common symptom of head trauma.

So my question is: could this moodiness be the result of her fall or is that unlikely given that the medics found no concussion?

Thank you,
