The thalamus is a crucial part of the brain that acts like a relay station, transmitting signals between different parts of the brain. When the thalamus doesn’t work properly, it can lead to various issues known as thalamus dysfunction. This dysfunction can cause a range of symptoms affecting both physical and mental health.
Types of Thalamus Dysfunction
- Sensory Thalamus Dysfunction: This type affects the processing of sensory information, leading to problems with perception, such as touch, temperature, and pain.
