The classification of aphasic patients’ symptoms into a syndrome is a crucial concept that favours and simplifies the communication among the clinicians involved in patient treatment and follow-up. Nevertheless, the aphasic population usually represents a very heterogeneous symptomatology; consequently, classical syndromes do not offer a good basis to plan their rehabilitation relying on their specific language impairments. Current rehabilitation strategies frequently require the identification of specific cognitive abilities affected. This is why it is common clinical practice to assess aphasic patients with a syndromic protocol in order to classify them as well as a cognitive battery to plan their rehabilitation. The aim of the present article is to present a quick and reliable tool (i.e., a syndromic classification sheet) to help clinician classify their clients in a syndrome by means of the use of only the cognitive neuropsychological assessment. Two groups of speech therapists (experienced and inexperienced) were asked to classify 5 aphasic patients from a syndromic classification sheet and their assessment protocols. Results indicate an acceptable inter-rater agreement for the experienced group but not for the inexperienced one. In conclusion, the classification sheet turned out to be a useful and reliable tool to classify aphasic patients in a given syndrome and by means of only some subtests from a cognitive assessment battery, provided that clinicians had some years of experience. In addition, this will enable language clinicians shorten the assessment of their aphasic clients.
