Abstract
Background and purpose: The main features of non-fluent aphasia are inadequate production, limited vocabulary and agrammatism. Such patients have deficits in sentence comprehension and production and their speech is short and telegraphic. In this study, morphological and syntactic errors in speech of non-fluent aphasia were compared with those in healthy subjects.
Materials and methods: A cross-sectional study was performed in 8 patients with non-fluent aphasia and 8 healthy individuals who were matched for age, sex and educational level. The morphological and syntactic structure of speech in healthy subjects and patients were elicited by two tasks (spontaneous speech and pictures description). Data analysis was conducted using the Mann-Whitney test.
Results: In spontaneous speech and pictures description significant differences were observed between healthy subjects and patients in average number of names (P=0.004). The average number of verbs showed significant difference between the two groups only in spontaneous speech (P=0.022). Also, other morphologic and syntactic elements such as the number of content and grammatical words, intransitive and transitive verbs, active and passive verbs, and mean length of utterance were significantly different between patients and healthy controls in both tasks
Conclusion: The results showed inappropriate use of syntactic and morphological structures in sentences by patients. Total number of grammatical words and content words were considerably lower in patients.

Abstract
Background and purpose: The Persian Diagnostic Aphasia Battery (P-DAB-1) is one of the tests available for screening and determining the severity of aphasia. The test classifies the patients in seven major diagnostic classes based on the extent of the impairment in different linguistic modalities. The present study aimed to describe the pattern of linguistic impairment in four aphasic patients according to the P-DAB-1 and compare that with the classical view of aphasia.
Materials and methods: The study was done in four Persian-speaking aphasic patients who were selected by convenience sampling. Inclusion criteria were being fluent in Persian and right-handed. Patients with severe untreated visual or hearing impairments and neurological diseases affecting cognition were excluded from the study. The P-DAB-1 test was used to determine the severity and type of aphasia.
Results: In this research, the participants had moderate aphasia quotient, of whom three had transcortical motor aphasia and one had conduction aphasia. The patients did not show some symptoms of a specific category according to the classical view.
Conclusion: This study proves the efficiency of P-DAB-1 test and also provides evidence for the deficiencies of the classical view in determining the types of aphasia.

Abstract
Background and purpose: Aphasia is the most common communication disorder resulting from stroke. In this condition all modalities of language, including reading, writing, auditory perception, and oral speech may be affected. Aphasia is divided into two categories: fluent (Wernicke's aphasia, Transcortical sensory aphasia, conduction aphasia, and anomic aphasia) and non-fluent (Broca's aphasia, global aphasia, transcortical motor aphasia, and mixed transcortical aphasia). As a result, the types of aphasia depend on the area of brain damage. In this study, the relationship between fluent aphasia and non-fluent aphasia with the brain damage area was investigated in stroke patients admitted to hospitals affiliated with Babol University of Medical Sciences in 2018.
Materials and methods: In this cross-sectional study, the diagnosis and discrimination of aphasia types were determined by performing the Persian version of the aphasia test and MRI/CT-scan images were taken to find the exact brain damage area. Data were analyzed in SPSS V26.
Results: We studied 123 patients. There were 70 cases with aphasia (mean age: 68.16 years), including 41 men and 29 women. Frontal lobes (25.7%) and temporal lobes (25.7%) were the most common brain regions affected.
Conclusion: Damage to the frontal lobe and its surrounding areas is associated with incidence of aphasia, and damage to the temporal lobe and its surrounding areas is linked to the occurrence of fluent aphasia.
