Visual dyslexia – there is a disorder known as disorder. Speech, attention, concentration and memory disorders may be present in dyslexia.

Dyslexia is characterised by a specific and significant impairment of the development of reading skills. If it affects a child, we speak of developmental dyslexia. A dyslexic person is confused by shapes, sounds, similar letters and similar sounding sounds. The cause of this disorder is disharmonious development in the cognitive sphere. Some researchers point to biological issues, some to genetic issues, others to damage within the CNS (central nervous system) during the foetal and perinatal period.
