Startle response. <br>Segment 1. In the first diagnostic test, the intention to tap the left arm (the visual stimulus) elicits a startle response that mainly consists of bilateral flexion of his arms. His legs are not involved. In the subsequent diagnostic tests, there is no reaction after a visual stimulus but a non-habituating startle reaction after tactile stimulation on his left arm. <br>Segment 2. Seven days after antibiotic treatment, there is no startle response after tactile stimulation on his chest or arms. However, a myoclonic response of the right sternocleidoid muscle after a gentle tap on the vertex can still be observed, which was no longer seen in the follow-up at two months.
