                                            Key factors in the neurological history     As per individual diagnosis.               As indicated below
The following diagnoses or symptoms         include:
are considered under Neurology:
                                            -       Neonatal History
-        Carpal tunnel and other            -       Drug History – including oral
         entrapment syndromes                       contraceptives
-        Headaches & Migraine               -       Head injury
-        Parkinsonism                       -       Previous intracranial infections
-        Progressive loss of Neurological   -       Alcohol
         function                           -       Family history
-        Movement Disorders                 -       Occupation
-        Neurological symptoms in           -       Pregnancy issues
         pregnancy                          -       Psychiatric and psychosocial
-        Seizures                                   history
-        Strokes & TIA
-        Tremor



The following conditions that are commonly referred to Neurology should be referred elsewhere in most cases:

Diagnosis or Symptoms                                                             Rationale:
Sleep Disorders / Narcolepsy                                                      Many of these conditions require a formal sleep study to make the diagnosis
Back Pain which has been fully investigated, with no surgical solution, and       A pain clinic would be more appropriate to address the problem with a multi-disciplinary approach
the patient is already taking medical therapy                                     and consider invasive therapies.
Elderly patients with complex medical problems                                    Referral to an Extended care physician is often more appropriate to address the multiple issues
                                                                                  including how the patient is managing in home /hostel.
