a individuated by their constituent properties, where the constituent properties are those the subject is inclined to predicate on the strength of his hallucination.38 Charles, who starts out as real and then is evidently unreal, (if I may put it that way) is not to be found among such this-worldly abstracta. Once again, even an abstract entity that includes the property of being first real and...

Topiramate (TPM) is an antiepileptic drug also used in migraine prophylaxis (Silberstein et al. 2007). Neuropsychiatric symptoms may emerge during the use of TPM (Fröscher et al. 2005). There are few reports showing a link between psychotic adverse events and use of TPM (Khan et al. 1999). Only one patient with schizoaffective disorder has been reported in the litera ture, who complained of dos...

We study stochastic control problems in the presence of hard wall constraints. Walls are incorporated in the dynamics of the agent by restricting its domain and hence perturbing the noise process close to the walls. A novel penalty term is introduced for bouncing off a wall. To efficiently search for a good policy we propose the “hallucination expectation maximization” algorithm which iterative...

A 76-year-old woman presented with catatonia, refusal to eat due to delusion, and visual hallucination. Single photon emission computed tomography showed remarkable occipital hypoperfusion and frontal hyperperfusion. (123)I metaiodobenzyl guanidine myocardial scintigraphy revealed decreased uptake. She was diagnosed as probable dementia with Lewy bodies (DLB). Intravenous or oral L-dopa had no ...

The concept of conversion hallucination is a relatively new one, however there have been several articles written on this phenomena, some attesting to it being a special form of hallucination while others dismissing it altogether. But currently this concept is slowly being accepted among psychiatrists and as such it is important for us to understand some of the concepts. In this case report, th...

Pre-trained language models (LMs) store knowledge in their parameters and can generate informative responses when used conversational systems. However, LMs suffer from the problem of “hallucination:” they may plausible-looking statements that are irrelevant or factually incorrect. To address this problem, we propose a contrastive learning scheme, named MixCL. A novel mixed objective is proposed...
