Exploding head syndrome (EHS) is an under-recognized parasomnia characterized by a complaint of sudden loud noise or a sense of explosion in the head that usually occurs at sleep onset. This paper is a report of 6 patients diagnosed with EHS through a structured clinical interview and video-polysomnography (vPSG) recordings. We also reviewed the available literature that addressed the presentation and clinical and PSG characteristics of EHS. The case series included 4 men and 2 women of a mean age of 44.2 years (between 13 and 77 years). Their episodes were variable in expression, between a sudden firecracker-like explosion to a gun-shot sound, mostly as if happening inside the head. EHS is always associated with distress but never with pain. Five out of 6 patients had other sleep-related problems with a close relationship of EHS symptoms to comorbid sleep disorder manifestations and exacerbations. The vPSG recordings of 5 patients were unremarkable. An attack of EHS was documented in 1 patient, arising during stage N2 of sleep. Three patients responded well to reassurance and treatment for the comorbid sleep disorder. The other 3 patients responded well to amitriptyline (10-50 mg). EHS is a well-characterized, underrecognized hypnic parasomnia with a benign course. Amitriptyline seems to be effective in persistent cases.

An explosive is a container that is filled with material that will explode when it is thrown or dropped, or when a device inside it makes it explode. Many materials can be used in making up of a bomb individually or when mixed with some other chemical. The type of explosive that gets misused most commonly are those used in manufacturing and other commercial applications due to their easy accessibility to public.

For the Leslie-Gower predator-prey model with Michaelis-Menten type prey harvesting, the known results are on the saddle-node bifurcation and the Hopf bifurcation of codimensions 1, the Bogdanov-Takens bifurcations of codimensions 2 and 3, and on the cyclicity of singular slow-fast cycles. Here, we focus on the global dynamics of the model in the slow-fast setting and obtain much richer dynamical phenomena than the existing ones, such as global stability of an equilibrium; an unstable canard cycle exploding to a homoclinic loop; coexistence of a stable canard cycle and an inner unstable homoclinic loop; and, consequently, coexistence of two canard cycles: a canard explosion via canard cycles without a head, canard cycles with a short head and a beard and a relaxation oscillation with a short beard. This last one should be a new dynamical phenomenon.

Exploding head syndrome (EHS) has historically been viewed as a disorder predominantly affecting older people and being more common in females. Through a comprehensive review of data since 2005, this scoping review provides updated evidence from 4082 participants reporting EHS across a variety of study designs on: how EHS presents; key information on comorbidity and correlates of EHS; how EHS is experienced in terms of symptoms and beliefs; causal theories arising from the research reviewed; and evidence-based information on how research has reported on the management of EHS. Since 2005, EHS has attracted increasing research interest; however, there are significant gaps in the research that are hindering a better understanding of EHS that might be helpful for clinicians.

Exploding head syndrome (EHS) is an uncommon sleeping disorder that is described by patients as a loud noise occurring while transitioning into and out of sleep. It is not accompanied by a headache but causes a sense of fright. We describe the case of a 58-year-old female patient, presenting with a total of 11 events of EHS occurring at bedtime.

- Non-REM parasomnias are common sleep disorders that occur when a person is partially awake and asleep, leading to behaviors like sleepwalking, sleep terrors, and sleep-related eating disorders, which can be triggered by factors like sleep deprivation and medications.
- These disorders can range from minor issues to serious problems, but they generally don't pose a significant risk to most individuals; however, safety should always be a priority for those affected.
- Management focuses on non-drug treatments such as improving sleep habits and addressing underlying issues, and medication like clonazepam may be considered if symptoms persist.
