“…Other techniques such as PACE [80], focus on the psychosocial and pragmatic aspects of communication. Several non-verbal methods for the treatment of severe global aphasics such as the visual analogue communication [81], iconic communication, visual action and drawing [82] therapies and amerind [20,74,75] are currently used. Special techniques were developed to improve speech apraxia [20,74,75].…”

“…Both of these assumptions arise from the notion that "spontaneous recovery" is occurring in the immediate period after stroke and may last as long as 1 year. [1][2][3][4] However, little is known about patterns of recovery beyond the recognized period of spontaneous physiological recovery. Individuals who are Ͼ1 ypo and who have demonstrated significant recovery are sometimes considered special nonrepresentative cases.…”

Background and Purpose-This article is a comprehensive review of aphasia treatment studies for the purpose of investigating the relationship between time postonset of aphasia and response to treatment for aphasia in chronic patients at Ն1 year after symptom onset. Methods-Studies that demonstrated treatment response (defined as a measurable change in task performance compared with a control task performance) through the use of single-subject design methodologies on measures of verbal output or auditory comprehension were selected. Individual subject data were extracted from the 23 studies that met criteria identifying the subjects as those who received direct continuous therapy for spoken language deficits and whose changes in response to therapy were measurable. Percent of maximum possible change was used as a measurement of outcome. Results-Nonparametric correlation statistics (Spearman ) and comparisons of group means (Kruskal-Wallis) were used to compare the relationship between time postonset and improvement. Time postonset at which treatment was initiated did not correlate with response to treatment. No significant differences in response to treatment were found between groups of patients according to times postonset. Conclusions-Time postonset is not related to response to treatment for aphasia in patients Ͼ1 year postonset of aphasia.

“…Moreover, since the increase in the RH perfusion (i.e., hypothetical right-sided release from inhibition) was associated both with significant improvement of language functioning (Table 2 and Table 3) and profound deficiency of the initial LH perfusion in the present study, we could expect, surprisingly, a better prognosis for aphasia in patients with a large brain lesion. Obviously, data from the literature suggest the reverse: Aphasic patients whose neuroimaging scans show large lesions are less likely to recover than those with smaller lesions (Sarno, 1998). In addition, we noted a relationship between degree of cerebral hypoperfusion and severity of aphasia, i.e., large brain infarcts produced language problems to a greater degree than smaller infarcts.…”

This prospective study examined the relationship between post-stroke recovery of aphasia and changes in cerebral blood flow (CBF). To address the question of right hemisphere (RH) involvement in restitution of language, we tested the hypothesis that the increase in perfusion of the RH is crucial for early recovery from aphasia. Twenty-four right-handed patients with acute aphasia following left hemisphere (LH) ischaemic stroke were examined twice with a six-month interval. At each session CBF and language scores were measured on the same stroke patients. Language was measured by selected tasks derived from the Boston Diagnostic Aphasia Examination (BDAE). The SPECT scans were obtained using (99m)Tc-ECD on a triple-head gamma camera Multispect-3. Although initial CBF measured for the whole group of aphasic patients was not a predictor for future language recovery for either hemisphere, increased perfusion of the RH during a six-month interval was found to parallel the recovery of aphasic disorders. There was a correlation between the change in the right parietal CBF (but not the left) and a change in numerous language abilities. Nevertheless, only CBF values on the left predicted performance on the language tests at initial and follow-up examinations. When the area damaged on structural imaging was excluded from perfusion analysis, only subcortical CBF change on the left showed a positive correlation with language improvement. Thus, the cerebral mechanism associated with early recovery from aphasia is a dynamic and complex process that may involve both hemispheres. Probably this mechanism involves functional reorganisation in the speech-dominant (damaged) hemisphere and regression of haemodynamic disturbances in the non-dominant (structurally intact) hemisphere.
