Untreated septic arthritis, which lead to destruction of the joint and bones
Ironically, the patient has a club foot deformity in the other foot, so he practically lost his ability to walk by now.

PNES: Psychogenic Non-Epileptic Seizure, also known as pseudo-seizure

Tongue biting is usually lateral in real seizures, but medial in PNES

Video-EEG monitoring is the “gold standard’’ for diagnosis of PNES. This is in contrast to other psychogenic symptoms, which are almost always a diagnosis of exclusion.
PNES should be suspected in all patients with frequent seizures despite taking medications. The combined electroclinical analysis of the clinical semiology being clearly incompatible with epileptic seizures and the ictal EEG being normal allow a definitive diagnosis in the vast majority of cases. Limitations of video-EEG monitoring include the fact that ictal EEG may be negative in some partial seizures or uninterpretable if movements generate excessive artifact.

Semiology of PNES include persistent eye closure at the onset of the attack, gradual onset; side-to-side head movements; pelvic thrusting; opisthotonic posturing; stuttering; weeping; pseudosleep; discontinuous (stop and go), irregular, or asynchronous (out of phase) activity; and gradual onset or termination.

The gaze in seizure (temporal vs extratemporal), syncope, and in PNES
Any seizure with eyes closed at the onset of the attack should raise suspicion for a psychogenic seizure. PNES are identified by the typical eye closure from the beginning and the long duration of the event, typically over 5 minutes, which are both very rare in epileptic seizures or syncope. Although closed eyes are typical for PNES, observing open eyes is not a reliable indicator for epileptic seizures. In fact, an upward gaze is often seen in patients having a syncopal episode.
Reflex seizure is a weird type of seizure where the patient will consistently have seizure every time he is exposed to a stimulus (the seizure becomes, in a way, like a reflex).
Flashing lights are the most common triggers, other triggers include music, reading, orgasm, certain points during the menstrual cycles, touching or moving a particular part of the body, ... etc

You can see the change in the baby's facial expressions, a myoclonus of the right arm (0:15) and the tonic seizure in its lower limbs afterwards.
The absence of all three signs of fever, neck stiffness and altered mental state virtually eliminates the diagnosis of meningitis in immunocompetent individuals.

The trigeminal nerve:
The cell bodies of the sensory fibres are located in the trigeminal ganglion. From the trigeminal ganglion, the main fibers (those responsible for touch, proprioception, and vibration) pass to the pons. but the pain and temperature pathways descend to the spinal cord, to around C2, where they make up the "spinal trigeminal nucleus." Then they ascend back into the thalamus.
