The film Cane Toads: An Unnatural History shows a male toad copulating with a female toad that had been run over by a car for eight hours. Necrophilic amplexus in frogs may occur because males will mount any pliable object the size of an adult female. If the mounted object is a live frog not appropriate for mating, it will vibrate its body or vocalise a call to be released. Dead frogs cannot do this, so they may be held for hours. The Amazonian frog Rhinella proboscidea sometimes practices what has been termed "functional necrophilia": a male grasps the corpse of a dead female and squeezes it until its oocytes are ejected before fertilising them. Treatment
Treatment for necrophilia is similar to that prescribed for most paraphilias. Besides advocating treatment of the associated psychopathology, there is little known on the treatment of necrophilia. There has not been a sufficient number of necrophiliacs to establish any effective treatments. However, based on the available data, clinicians are suggested to:

Determine whether or not a patient has necrophilia
Treat any psychopathology that is associated with necrophilia
Establish psycho-therapeutic rapport
Provide male patients with heightened sex drives with anti-androgens
Help patients find a normal sexual relationship
Help divert the necrophilic fantasies to a living object via desensitization

Case studies
Jeffrey Dahmer
Serial killer Jeffrey Dahmer (1960–1994) was known to perform oral sex or masturbate, or both, upon the corpses of his victims before dismembering them.
Moreover, the abnormal behavioural symptoms of the disease negatively contribute to overwhelming patients relatives and caregivers as well.However, the impact of sleep-wake disturbances on the subjective experience of a person with AD is not yet fully understood. Therefore, further studies exploring this field have been highly recommended, mainly considering the increasing life expectancy and significance of neurodegenerative diseases in clinical practices. Treatment
Possible treatments for circadian rhythm sleep disorders include:

Chronotherapy, best shown to effectively treat delayed sleep phase disorder, acts by systematically delaying an individuals bedtime until their sleep-wake times coincide with the conventional 24-hr day. Light therapy utilizes bright light exposure to induce phase advances and delays in sleep and wake times. This therapy requires 30–60 minutes of exposure to a bright (5,000–10,000 lux) white, blue, or natural light at a set time until the circadian clock is aligned with the desired schedule. Treatment is initially administered either upon awakening or before sleeping, and if successful may be continued indefinitely or performed less frequently. Though proven very effective in the treatment of individuals with DSPD and ASPD, the benefits of light therapy on N24SWD, shift work disorder, and jet lag have not been studied as extensively. Hypnotics have also been used clinically alongside bright light exposure therapy and pharmacotherapy for the treatment of CRSDs such as Advanced Sleep Phase Disorder. Additionally, in conjunction with cognitive behavioral therapy, short-acting hypnotics also present an avenue for treating co-morbid insomnia in patients with circadian sleep disorders.
