The use of antibiotics to prevent meningitis in those with a CSF leak due to a skull fracture is of unclear benefit. Prognosis
Long-term outcomes for people with SCSFLS remain poorly studied. Symptoms may resolve in as little as two weeks, or persist for months. Less commonly, patients may have unremitting symptoms for many years. People with chronic SCSFLS may be disabled and unable to work. Recurrent CSF leak at an alternate site after recent repair is common. Epidemiology
A 1994 community-based study indicated that two out of every 100,000 people with SCSFLS, while a 2004 emergency room-based study indicated five per 100,000. SCSFLS generally affects the young and middle aged; the average age for onset is 42.3 years, but onset can range from ages 22 to 61. In an 11-year study, women were found to be twice as likely to be affected as men.Studies have shown that SCSFLS runs in families. It is suspected that genetic similarity in families includes weakness in the dura mater which leads to SCSFLS. Large scale population-based studies have not yet been conducted. While a majority of SCSFLS cases continue to be undiagnosed or misdiagnosed, an actual increase in occurrence is unlikely. History
Spontaneous CSF leaks have been described by notable physicians and reported in medical journals dating back to the early 1900s. German neurologist Georg Schaltenbrand reported in 1938 and 1953 what he termed "aliquorrhea", a condition marked by very low, unobtainable, or even negative CSF pressures.
Restricted emotions and interpersonal functioning
Individuals with this disorder may display little affection and warmth; their relationships and speech tend to have a formal and professional approach, and not much affection is expressed even to loved ones, such as greeting or hugging a significant other at an airport or train station.They are extremely careful in their interpersonal interactions. They have little spontaneity when interacting with others, and ensure that their speech follows rigid and austere standards by excessively scrutinising it. They filter their speech for embarrassing or imperfect articulation, and they have a low bar for what they consider to be such. They lower their bar even further when they are communicating with their superiors or with a person of high status. Communication becomes a time-consuming and exhausting effort, and they start avoiding it altogether. Others regard them as cold and detached as a result.Their need for restricting affection is a defense mechanism used to control their emotions. They may expunge emotions from their memories and organize them as a library of facts and data; the memories are intellectualized and rationalized, not experiences that they can feel. This helps them avoid unexpected emotions and feelings and allows them to remain in control. They view self-exploration as a waste of time and have a patronising attitude towards emotional people. Interpersonal control
Individuals with OCPD are at one extreme of the conscientiousness continuum. While conscientiousness is a desirable trait generally, its extreme presentation for those with OCPD leads to interpersonal problems.
