In his early publications Berlin described the dyslexia of individuals who had shed their capacity to check out due to brain damage. Nonetheless, in 1917 he upgraded the notes on two of these patients and given no scientific descriptors which communicated their dyslexia. Furthermore, his interest remained in expression, stammering and writing not in analysis.
