Common symptoms of head injury include coma, confusion, drowsiness, personality change, seizures, nausea and vomiting, headache and a lucid interval, during which a patient appears conscious only to deteriorate later.Symptoms of skull fracture can include:

leaking cerebrospinal fluid (a clear fluid drainage from nose, mouth or ear) is strongly indicative of basilar skull fracture and the tearing of sheaths surrounding the brain, which can lead to secondary brain infection. visible deformity or depression in the head or face; for example a sunken eye can indicate a maxillar fracture
an eye that cannot move or is deviated to one side can indicate that a broken facial bone is pinching a nerve that innervates eye muscles
wounds or bruises on the scalp or face. Basilar skull fractures, those that occur at the base of the skull, are associated with Battles sign, a subcutaneous bleed over the mastoid, hemotympanum, and cerebrospinal fluid rhinorrhea and otorrhea.Because brain injuries can be life-threatening, even people with apparently slight injuries, with no noticeable signs or complaints, require close observation; They have a chance for severe symptoms later on. The caretakers of those patients with mild trauma who are released from the hospital are frequently advised to rouse the patient several times during the next 12 to 24 hours to assess for worsening symptoms. The Glasgow Coma Scale (GCS) is a tool for measuring the degree of unconsciousness and is thus a useful tool for determining the severity of the injury. The Pediatric Glasgow Coma Scale is used in young children.
It is difficult to gain rapport with people with STPD due to the fact that increasing familiarity and intimacy usually increase their level of anxiety and discomfort.Group therapy is recommended for persons with STPD only if the group is well structured and supportive. Otherwise, it could lead to loose and tangential ideation. Support is especially important for schizotypal patients with predominant paranoid symptoms, because they will have a lot of difficulties even in highly structured groups. Comorbidity
Schizotypal personality disorder frequently co-occurs with major depressive disorder, dysthymia and social phobia. Furthermore, sometimes schizotypal personality disorder can co-occur with obsessive–compulsive disorder, and its presence appears to affect treatment outcome adversely. Some people with a clinical diagnosis of OCD have been found to also possess many schizotypal personality traits resulting in what can be called ‘schizotypal OCD’. Without proper treatment, STPD tendencies, such as magical thinking and paranoid ideation, could worsen the symptoms of OCD in an individual. There may also be an association with bipolar disorder. People with Gilles de la Tourette syndrome (GTS) can commonly possess some schizotypal traits.In terms of comorbidity with other personality disorders, schizotypal personality disorder has high comorbidity with schizoid and paranoid personality disorder, the other two Cluster A conditions. It also has significant comorbidity with borderline personality disorder and narcissistic personality disorder.Some schizotypal people go on to develop schizophrenia, but most of them do not. There are dozens of studies showing that individuals with schizotypal personality disorder score similar to individuals with schizophrenia on a very wide range of neuropsychological tests.
