Unfortunately, based on the information given alone, it is very difficult to ascertain why you believe that your husband has an intracranial abscess
rather than some of the other possibilities for these symptoms. The complete differential diagnosis for lack of coordination or clumsiness is beyond the scope of this discussion, but things to look for when concerned for intracranial abscess include recent fevers, neck stiffness, ear or sinus infections, sick contacts or infections on other parts of the body.
Although intracranial abscess is on the differential for clumsiness and lack of coordination, there are many other diagnoses that may be more likely if your husband has not had some of the other risk factors for intracranial abscess. It is important that you discuss these concerns and any other neurological issues with your primary care doctor
who will be best able to evaluate your husbands medical history, presenting symptoms and clinical exam and decide upon the appropriate work up. This may include imaging studies and lab tests. He or she may also refer you to a specialist for further evaluation and work up. If this turns out to be an intracranial abscess, the treatment options can be discussed with you primary care doctor.
