Table 2.

Patient categorization based on disorder-presence/-absence across the 3 types of disorders and the corresponding patient frequency (number of patients [%])

Type	Aphasia	Dysarthria	Cognitive dysfunction	Patients (n = 314)
A	✓	✓	✓	26 (8.3)
B	✓	✓	+	7 (2.2)
C	✓	+	✓	37 (12.8)
D	✓	+	+	22 (7.0)
E	+	✓	✓	67 (21.3)
F	+	✓	+	54 (17.2)
G	+	+	✓	49 (15.6)
H	+	+	+	52 (16.6)

There were 8 categories according to the presence or absence of aphasia, dysarthria, and cognitive-related communicative dysfunction (cognitive dysfunction). Aphasia was present in patient types A–D (n = 92) and absent in patient types E–H (n = 222). Dysarthria was present in patient types A, B, E, and F (n = 154) and absent in patient types C, D, G, and H (n = 160). Cognitive dysfunction was present in patient types A, C, E, and G (n = 179) and absent in patient types B, D, F, and H (n = 135).
