“…In a younger girl, reported previously more in detail [12], who suffered from 40-50 attacks per day, we observed a dramatic improvement with the use of carmamazepine, after several attempts with NSAIDs. This could suggest a paroxysmal neuronal discharge, like a trigeminal neuralgia [13].…”

“…Polyopia is an uncommon visual phenomenon and an infrequent symptom of central nervous system disease, mainly occipital or temporal lesions [ 36 ], often associated with palinopsia, defined as the perception of many copies of objects or faces [ 37 ]. An interesting case report with a child affected by polioplia associated with the hemianopsia during migraine attack has been described in children affected by migraine [ 38 , 39 ]…”

Since the earliest descriptions of the simple visual hallucinations in migraine patients and in subjects suffering from occipital lobe epilepsy, several important issues have arisen in recognizing epileptic seizures of the occipital lobe, which often present with symptoms mimicking migraine. A detailed quantitative and qualitative clinical scrutiny of timing and characteristics of visual impairment can contribute to avoiding mistakes. Differential diagnosis, in children, might be challenging because of the partial clinical, therapeutic, and pathophysiological overlaps between the two diseases that often coexist. Ictal elementary visual hallucinations are defined by color, shape, size, location, movement, speed of appearance and duration, frequency, and associated symptoms and their progression. The evaluation of the distinctive clinical features of visual aura in migraine and visual hallucinations in occipital epilepsy could contribute to understanding the pathogenetic mechanisms of these two conditions. This paper aims to critically review the available scientific evidence on the main clinical criteria that address diagnosis, as well as similarities and differences in the pathophysiological mechanisms underlying the visual impairment in epilepsy and migraine.

“…Polyopia has been described before with occipital lobe disease due to trauma, ischemia, epilepsy, and migraine [ 2 - 5 ]. We also reviewed potential mechanisms including cortical spreading depression and abnormal visual synthesis, and we posited a new hypothesis: the holonomic brain theory [ 1 ].…”

All reported cases of cerebral polyopia in the literature are associated solely with occipital lobe disease, as seen with ischemic infarcts, migraine, trauma, and epilepsy. To our knowledge, this is the first case of polyopia associated with posterior parietal cortex (PPC) ischemic infarct to be reported in the literature. Previous hypotheses about mechanisms of polyopia have included cortical spreading depression, the vague idea of abnormal visual synthesis, and the holographic or holonomic brain theory. We propose a new mechanism due to dysfunction of the network from the PPC \begin{document}\rightarrow\end{document} frontal eye field (FEF) \begin{document}\rightarrow\end{document} paramedian midbrain and pontine reticular formation leading to convergence insufficiency, which leads to horizontal diplopia. The evidence ranging from tracer studies in macaque monkeys to functional MRI (fMRI) studies in patients with convergence insufficiency is presented to bolster our hypothesis. In the process, we also briefly review the neural pathways of convergence.
