Ted Bundy, Jeffrey Dahmer
Category B (cold/preservative), e.g. Gary Ridgway, Dennis Nilsen, Carl Tanzler
Category C (warm/destructive) e.g. Andrei Chikatilo, Joseph Vacher
Category D (warm/preservative) e.g. Robert Yates, Earle Nelson
Category E (dabblers) e.g. Richard Ramirez, Mark Dixie
Category F (catathymic⁠ ⁠— impulsively and explosively lashing out)
Category G (exclusive necromutilophiles) e.g. Robert Napper, Peter Sutcliffe
Category H (sexual cannibals & vampires) e.g. Albert Fish, Peter KürtenDabblers have transitory opportunistic sexual relations with corpses, but do not prefer them. Catathymic necrophiliacs commit postmortem sex acts only while in a sudden impulsive state. Exclusive necromutilophiles derive pleasure purely from mutilating the corpse, while sexual cannibals and vampires are sexually aroused by eating human body parts. Category A, C, and F offenders may also cannibalise or drink the blood of their victims. Research
Humans
Necrophilia is often assumed to be rare, but no data for its prevalence in the general population exists. Some necrophiliacs only fantasise about the act, without carrying it out. In 1958, Klaf and Brown commented that, although rarely described, necrophiliac fantasies may occur more often than is generally supposed.Rosman and Resnick (1989) reviewed 123 cases of necrophilia. The sample was divided into genuine necrophiliacs, who had a persistent attraction to corpses, and pseudo-necrophiliacs, who acted out of opportunity, sadism, or transient interest. Of the total, 92% were male and 8% were female. 57% of the genuine necrophiliacs had occupational access to corpses, with morgue attendants, hospital orderly, and cemetery employees being the most common jobs.
Because of this, primidone is a Category D medication.Primidone, like phenobarbital and the benzodiazepines, can also cause sedation in the newborn and also withdrawal within the first few days of life; phenobarbital is the most likely out of all of them to do that.In May 2005, Dr. M. Lopez-Gomezs team reported an association between the use of primidone and depression in epilepsy patients; this same study reported that inadequate seizure control, posttraumatic epilepsy, and polytherapy were also risk factors. Polytherapy was also associated with poor seizure control. Out of all of the risk factors, usage of primidone and inadequate seizure control were the greatest; with ORs of 4.089 and 3.084, respectively. They had been looking for factors associated with depression in epilepsy patients. Schaffer et al. 1999 reported that one of their treatment failures, a 45-year-old woman taking 50 mg a day along with lithium 600 mg/day, clozapine 12.5 mg/day, trazodone 50 mg/day, and alprazolam 4 mg/day for three and a half months experienced auditory hallucinations that led to discontinuation of primidone. It can also cause hyperactivity in children; this most commonly occurs at low serum levels. There is one case of an individual developing catatonic schizophrenia when her serum concentration of primidone went above normal.Primidone is one of the anticonvulsants associated with anticonvulsant hypersensitivity syndrome, others being carbamazepine, phenytoin, and phenobarbital.
