We describe a 44-year-old Chinese-speaking patient with semantic dementia (SD), who demonstrates dyslexia and dysgraphia. The man was administered a series of neuropsychological inspections, including general language tests and reading and writing examinations. The patient demonstrated surface dyslexia when reading single Chinese characters aloud. While most writing errors demonstrated by the patient were orthographically similar errors and noncharacter responses, such as pictograph, logographeme, and stroke errors, rather than phonologically plausible errors that were homophonous or different only in tone from the targets. We suggest that the type of acquired dysgraphia demonstrated by Chinese-speaking SD patients is determined by the unique features of the Chinese writing system.

Background: Learning disabilities, categorized as neurodevelopmental disorders, profoundly impact the cognitive development of young children. These disabilities affect text comprehension, reading, writing and problem-solving abilities. Specific learning disabilities (SLDs), most notably dyslexia and dysgraphia, can significantly hinder students' academic achievement.

Article Synopsis
- This study investigates how language-specific features affect primary progressive aphasia (PPA) symptoms in Italian and English speakers, diverging from the traditionally English-focused research.
- A comparison was made between 106 Italian speakers and 166 English speakers with various PPA syndromes, highlighting differences in demographic factors and symptom profiles.
- Results showed significant variations between the cohorts, with English speakers having a higher proportion of nonfluent/agrammatic PPA cases and different patterns of language comprehension and production issues compared to Italian speakers.

Surface dyslexia and dysgraphia are considered diagnostic features of semantic variant primary progressive aphasia (svPPA) and are useful signs in English, a language whose attributes afford numerous opportunities to observe these phenomena. This, however, is not the case in many languages, including Italian, that have high transparency between orthography and phonology, making surface reading and spelling errors scarce. This creates a problem in applying the diagnostic recommendations for svPPA in such languages.

The variants of heterotypic comorbidity of anxiety disorders (AD) with attention deficit hyperactivity disorder, autism spectrum disorders, speech and language development disorders, specific learning disabilities (dyslexia, dysgraphia, dyscalculia), migraine, tension type headache in children and adolescents are discussed. In cases of heterotypic comorbidity the patients with AD referrals to specialists may be primarily associated with their emotional problems. Meanwhile, the comorbidity of AD with these diseases leads to a deterioration of their clinical manifestations and a worsening of the prognosis, and anxiety symptoms often not only persist, but also increase with age.
