Deaf and self-signing

Thought disorders in deaf psychiatric in­patients are difficult to diagnose, in part because of a high rate of language dysflu­ency in deaf patients; in samples of psychi­atric inpatients, 75% are not fluent in ASL, 66% are not fluent in any language).^1,3,11 Commonly, language dysfluency is related to language deprivation because of late or inadequate exposure to ASL, although it may be related to neurologic damage or aphasia.^1,3,6,16 Deaf patients can have addi­tional disabilities, including learning dis­abilities, that might contribute to language dysfluency.² Language dysfluency can be misattributed to a psychotic process^1-3,7 (Table 3).¹

Language dysfluency and thought dis­orders can be difficult to differentiate and may be comorbid. Loose associations and flight of ideas can be hard to assess in pa­tients with language dysfluency. In general, increasing looseness of association between concepts corresponds to an increasing like­lihood that a patient has true loose asso­ciations rather than language dysfluency alone.³ Deaf patients with schizophrenia can be identified by the presence of associ­ated symptoms of psychosis, especially if delusions are present.^1,3

EVALUATION Psychotic symptoms
Mrs. H’s thought process appears disorganized and illogical, with flight of ideas. She might have an underlying language dysfluency. It is likely that Mrs. H is using neologisms to communi­cate because of her family’s lack of familiarity with some of her signs. She also demonstrates perseveration, with use of certain signs repeat­edly without clear context (ie, “nothing off”).

Her thought content includes racial themes—she mentions Russia, Germany, and Vietnam without clear context—and delusions of being the “star king” and of being pregnant. She endorses paranoid feelings that people on the inpatient unit are trying to hurt her, al­though it isn’t clear whether this represents a true paranoid delusion because of the hectic climate of the unit, and she did not show unnecessarily defensive or guarded behaviors.

She is seen signing to herself in the dayroom and endorses feeling as though someone who is not in the room—described as an Indian teacher (and sometimes as a boss or principal) known as “Mr. Smith” or “Mr. Donald”—is trying to communicate with her. She describes this person as being male and female. She men­tions that sometimes she sees an Indian man and another man fighting. It is likely that Mrs. H is experiencing hallucinations from decompen­sated psychosis, because of the constellation and trajectory of her symptoms. Her nonverbal behavior—her eyes rove around the room dur­ing interviews—also supports this conclusion.

Because of evidence of mood and psychotic symptoms, and with a collateral history that suggests significant baseline disorganization, Mrs. H receives a diagnosis of schizoaffective disorder, bipolar type. She is restarted on olan­zapine, 10 mg/d, and valproic acid, 1,000 mg/d.

Mrs. H’s psychomotor acceleration and af­fective elevation gradually improve with phar­macotherapy. After a 2-week hospitalization, despite ongoing disorganization and self-sign­ing, Mrs. H’s husband says that he feels she is improved enough to return home, with plans to continue to take her medications and to re­establish outpatient follow-up.

Bottom Line

Psychiatric assessment of deaf patients presents distinctive challenges related to cultural and language barriers—making it important to engage an ASL interpreter with training in mental health during assessment of a deaf patient. Clinicians must become familiar with these challenges to provide effective care for mentally ill deaf patients.
