We sought to show that (1) schizotaxia (Meehl's term for the predisposition
to schizophrenia) is a clinically consequential condition, and (2) disting
uishing it from schizotypal personality disorder may be useful from both cl
inical and scientific perspectives. We review the features of schizotaxia t
hat may be relevant in clinical settings and discuss their implications for
the diagnosis, psychosocial functioning, family intervention and treatment
of people in schizophrenia families. Our review indicates that prior work
finds some of the nonpsychotic and nonschizotypal relatives of schizophreni
a patients to have a psychiatric syndrome characterized by negative symptom
s, neuropsychological impairment, and psychosocial dysfunction, Following M
eehl, we call this constellation of clinical and neurobiological features s
chizotaxia, The studies we review suggest it may be worthwhile to consider
schizotaxia as a separate diagnostic class. Doing so would alert clinicians
to a neurobehavioral syndrome not adequately covered by current diagnostic
criteria and would motivate researchers to develop diagnostic and therapeu
tic approaches aimed at helping schizotaxic individuals and, perhaps, preve
nting the onset of schizophrenia.
