Thank you for posting your query.
I have noted your symptoms, and would like to reassure you that post concussion syndrome resolves in most people. The time frame for recovery varies, but complete recovery occurs in most people within 3-6 months.
Panic attacks or anxiety are not part of post concussion syndrome.
Medications such as clonazepam would help you relieve anxiety or panic. Piracetam tablets would help improve memory and concentration.
Continue vestibular adaptation exercises under the guidance of a physical therapist. Also, you can take betahistine tablets, as and when you feel dizzy.
