ABSTRACT: Aim: To explore what is the relationship of
the types of post-stroke aphasia with sex, age and stroke types. Methods: Retrospective analysis was administrated
on data of 421 patients with acute stroke.
Western battery aphasia was used to measure aphasiac type and aphasia quotient
(AQ) score. The patients were
divided into three age groups: young, middle-aged and elderly. The stroke types were classified into cerebral
infraction (CI) and intracerebral hemorrhage (ICH). Results: All subjects were
right-handed, which males and females accounted for 69.60% and 30.40%,
respectively. There were 116 cases of Broca’s aphasia (85 males), 35 cases of
Wernicke’s aphasia (20 males), 15
cases of conductive aphasia (10 males), 63 cases of transcortical motor aphasia
(50 males), 11 cases of transcortical sensory aphasia (8 males), 27 cases of
transcortical combined aphasia (13 males), 73 cases of anomic aphasia (47 males)
and 81 cases of global aphasia (60 males). Male patients (69.60%) have a
significantly higher morbidity of aphasia than that of females (30.40%) after
stroke (χ2 =
11.57, P = 0.003),
especially those under 65 years old (73.38%). For people 65 years and older, the morbidity of female
(42.97%) tends to increase with age. Sex has no significant influence on the
types of aphasia (χ2 =
13.84, P = 0.054). Broca’s aphasia is the most
common type inboth male and female (29.01%, 24.22%, respectively). The distribution
of aphasic types has no obvious difference among three age groups (χ2 = 14.94, P= 0.382). Aphasia induced by
CI (306 cases) is more common
than that by ICH (115 cases), but there was no difference in distribution of
types of aphasia (χ2 =
13.23, P = 0.067). Conclusions: Male patients
have a significantly higher level of morbidity of aphasia than females after
stroke and a lower average age of onset than females. Broca’s aphasia is the most common one in both
male and female. Broca’s aphasia, global and anomic aphasia are the most common aphasic types in
both CI and ICH patients, except the female with ICH.
