TYPES
There are 13 different forms of the Spielmeyer-Vogt disease, according to researchers and healthcare professionals. They identify the types depending on the age at which symptoms appear and the gene that has changed. Moreover, this disease’s signs and symptoms may appear in infancy, late infancy, childhood, or the early years of teenagers.
SYMPTOMS
As the illness progresses, the impact may occur on the vision, motor abilities, speech, cognition, and language. Although, vision problems begin before children enter school, and by their early adolescent years, the majority of patients are unable to see. With poor balance and bent-knee walking, motor abilities deteriorate and reflexes become more rigid.
Moreover, many people acquire epilepsy, as well as neuropsychiatric symptoms, including obsessive behavior and attention problems. For instance, nightmares, sleep disorders, fear, anxiety, and aggression can be experienced by the patient with Spielmeyer-Vogt disease.
