Chant-like speech is most often seen in cerebellar earthworm damage and cerebellar degenerative disorders. In multiple sclerosis, 10% to 15% of patients have such difficulties in dysarthria and chant-like speech. The following tests are required for gibberish-like language: EEG EEG is the basis of the physiological functions of the brain. The application of EEG is no longer limited to neurological diseases, but has been widely used for monitoring critical patients in various departments, anesthesia monitoring, and psychological and behavioral studies. In addition to routine EEG, there are long-term EEG monitoring, video EEG monitoring, sleep monitoring and digital computer analysis. EEG spike wave EEG spike wave is a kind of triangular wave with a time limit between 80 and 300 MS, the shape is fast and straight up and slow down, the wave amplitude can be more than 200μV, it is also a kind of pathological wave, it is a cortical stimulation phenomenon, mostly seen in epilepsy. During the examination, do not be nervous, place receiving electrodes on the scalp, not energized; relax the muscles of the whole body to avoid interference with myoelectricity; open the eyes, close the eyes or hyperventilate as requested by the doctor. Nuclear magnetic resonance NMR (NuclearMagneticResonance) is nuclear magnetic resonance. It is a physical process in which an atomic nucleus with a non-zero magnetic moment, under the action of an external magnetic field, undergoes Zeeman splitting of the spin energy level and resonantly absorbs a certain frequency of radio frequency radiation. MRI has the characteristics of multi-directional tangential layer and multi-parameter imaging, which can be more accurate in realistic lesion location, scope size and histological characteristics, and is the preferred method to discover structural lesions inside the brain. CT brain examination CT brain examination is a method of examining the cranial brain through CT. In the case of head trauma, brain CT is the most important diagnostic imaging method.
