Risk factors for schizophrenia - Intro to Psychology

  • 0:00 - 0:05
    So we see that the more closely
    a person is related to someone
  • 0:05 - 0:07
    who suffers from schizophrenia.
  • 0:07 - 0:11
    The more likely that person is also
    to suffer from the disorder.
  • 0:11 - 0:15
    So we know from this that there is
    a genetic component to schizophrenia,
  • 0:15 - 0:17
    but by itself that's not enough.
  • 0:17 - 0:21
    There also has to be some kind of
    stressful environmental experience
  • 0:21 - 0:23
    that the person suffers from.
  • 0:23 - 0:28
    Those two things together are really
    what's required and we refer to this
  • 0:28 - 0:31
    as the diathesis stress model.
  • 0:31 - 0:34
    So, diathesis means
    the biological predisposition
  • 0:34 - 0:37
    and the stress means some kind
    of environmental event.
  • 0:37 - 0:39
    It's those two things together
    that are really required.
  • 0:39 - 0:43
    And this, by the way, applies to all kinds
    of psychological disorders.
  • 0:43 - 0:48
    Anxiety, personality disorders,
    obsessive compulsive disorders.
  • 0:48 - 0:52
    So, let's take a closer look at some
    of the seenvironmental risk factors
  • 0:52 - 0:54
    for schizophrenia.
  • 0:54 - 0:58
    So one of the risk factors involved
    in the development of schizophrenia
  • 0:58 - 1:01
    is maternal infection.
  • 1:01 - 1:06
    And so what we mean by this is that
    if a pregnant woman is exposed to diseases
  • 1:06 - 1:12
    or infections, that the baby, later on
    in life, actually has an increased risk
  • 1:12 - 1:15
    for the development of schizophrenia.
  • 1:15 - 1:19
    So some of these diseases and infections
    include things like herpes,
  • 1:19 - 1:23
    influenza, rubella and toxoplasmosis.
  • 1:23 - 1:28
    And toxoplasmosis by the way is found
    in feline feces which is one reason
  • 1:28 - 1:29
    why doctors always recommend
  • 1:29 - 1:33
    that pregnant women
    stay away from cat litter.
  • 1:33 - 1:37
    Other environmental risk factors
    include chronic stress
  • 1:37 - 1:40
    and taking certain drugs, now again,
  • 1:40 - 1:44
    by themselves, these things do not cause
    or even really increase schizophrenia.
  • 1:44 - 1:48
    It's that coupled with
    a genetic predisposition
  • 1:48 - 1:50
    that's really required.
  • 1:50 - 1:54
    And again this is what we mean
    by the diathesis stress model.
