All You Need to Know About Agnosia
Agnosia is a Greek word which means ‘absence of knowledge’. This term was coined by ‘Sigmund Freud’ in 1891. Agnosia is a neurological disorder which is characterized by a loss of ability to recognize things. Here, the person is unable to perceive the objects, persons, places, shapes, sounds, and smells. The interesting fact is, all the senses are intact and there is no defect at all but due to some defect in the brain like- damage of occipitotemporal border, which may occur because of head injury, a person may lose these sensory abilities. But agnosia will affect only a single modality at a time, it’s either auditory, speech or vision. In this condition, a person who is affected by agnosia can interact with the world normally. There are different types of agnosia.
As per Ayurveda, this is a Tridoshaj Vyadhi with the predominance of Vata dosha which affects all the dhatus especially the majja dhatu of the brain.
