AOS and expressive aphasia (also known as Broca's aphasia) are commonly mistaken as the same disorder mainly because they often occur together in patients. Although both disorders present with symptoms such as a difficulty producing sounds due to damage in the language parts of the brain, they are not the same. The main difference between these disorders lies in the ability to comprehend spoken language; patients with apraxia are able to fully comprehend speech, while patients with aphasia are not always fully able to comprehend others' speech.

Conduction aphasia is another speech disorder that is similar to, but not the same as, apraxia of speech. Although patients who suffer from conduction aphasia have full comprehension of speech, as do AOS sufferers, there are differences between the two disorders. Patients with conduction aphasia are typically able to speak fluently, but they do not have the ability to repeat what they hear.

Similarly, dysarthria, another motor speech disorder, is characterized by difficulty articulating sounds. The difficulty in articulation does not occur due in planning the motor movement, as happens with AOS. Instead, dysarthria is caused by inability in or weakness of the muscles in the mouth, face, and respiratory system.

There are three significant features that differentiate DVD/CAS from other childhood speech sound disorders. These features are:

- "Inconsistent errors on consonants and vowels in repeated productions of syllables and words

- Lengthened coarticulatory transitions between sounds and syllables

- Inappropriate prosody, especially in the realization of lexical or phrasal stress"

Even though DVD/CAS is a "developmental" disorder, it will not simply disappear when children grow older. Children with this disorder do not follow typical patterns of language acquisition and will need treatment in order to make progress.

Apraxia of speech (AOS) is a neurogenic communication disorder affecting the motor programming system for speech production. Individuals with AOS demonstrate difficulty in speech production, specifically with sequencing and forming sounds. The Levelt model describes the speech production process in the following three consecutive stages: conceptualization, formulation, and articulation. According to the Levelt model, apraxia of speech would fall into the articulation region. The individual does not suffer from a language deficiency, but has difficulty in the production of language in an audible manner. Notably, this difficulty is limited to vocal speech, and does not affect sign-language production. The individual knows exactly what they want to say, but there is a disruption in the part of the brain that sends the signal to the muscle for the specific movement. Individuals with acquired AOS demonstrate hallmark characteristics of articulation and prosody (rhythm, stress or intonation) errors. Coexisting characteristics may include groping and effortful speech production with self-correction, difficulty initiating speech, abnormal stress, intonation and rhythm errors, and inconsistency with articulation.

Wertz et al., (1984) describe the following five speech characteristics that an individual with apraxia of speech may exhibit:

- Effortful trial and error with groping

- Self correction of errors

- Abnormal rhythm, stress and intonation

- Inconsistent articulation errors on repeated speech productions of the same utterance

- Difficulty initiating utterances

Developmental verbal dyspraxia (DVD), also known as childhood apraxia of speech (CAS) and developmental apraxia of speech (DAS), is when children have problems saying sounds, syllables, and words. This is not because of muscle weakness or paralysis. The brain has problems planning to move the body parts (e.g., lips, jaw, tongue) needed for speech. The child knows what they want to say, but their brain has difficulty coordinating the muscle movements necessary to say those words. The exact cause of this disorder is unknown. Some observations suggest a genetic cause of DVD, as many with the disorder have a family history of communication disorders. There is no cure for DVD, but with appropriate, intensive intervention, people with this motor speech disorder can improve significantly.

Developmental verbal dyspraxia (DVD) is a type of ideational dyspraxia, causing speech and language impairments. This is the favoured term in the UK; however, it is also sometimes referred to as articulatory dyspraxia, and in the United States the usual term is childhood apraxia of speech (CAS).

Key problems include:

- Difficulties controlling the speech organs.

- Difficulties making speech sounds

- Difficulty sequencing sounds

- Within a word

- Forming words into sentences

- Difficulty controlling breathing, suppressing salivation and phonation when talking or singing with lyrics.

- Slow language development

Dysarthria is the reduced ability to motor plan volitional movements needed for speech production as the result of weakness/paresis and/or paralysis of the musculature of the oral mechanism needed for respiration, phonation, resonance, articulation, and/or prosody.

Fine-motor problems can cause difficulty with a wide variety of other tasks such as using a knife and fork, fastening buttons and shoelaces, cooking, brushing one's teeth, styling one's hair, shaving, applying cosmetics, opening jars and packets, locking and unlocking doors, and doing housework.

Difficulties with fine motor co-ordination lead to problems with handwriting, which may be due to either ideational or ideo-motor difficulties.

Problems associated with this area may include:

- Learning basic movement patterns.

- Developing a desired writing speed.

- Establishing the correct pencil grip

- The acquisition of graphemes – e.g. the letters of the Latin alphabet, as well as numbers.

There are two types of Apraxia. Developmental (or Childhood Apraxia of speech) or acquired Apraxia. Childhood apraxia of speech (CAS) is a neurological childhood speech sound disorder that involves impaired precision and consistency of movements required for speech production without any neuromuscular deficits (ASHA, 2007a, Definitions of CAS section, para. 1). Both are the inability to plan volitional motor movements for speech production in the absence of muscular weakness. Apraxia is not a result of sensory problems, or physical issues with the articulatory structures themselves, simply the way the brain plans to move them.

The Lance Armstrong doping case was a doping investigation that led to American former professional road racing cyclist Lance Armstrong being stripped of his seven Tour de France titles and his eventual admission to the doping.

Doping in Russian sports has a systemic nature. Russia has had 51 Olympic medals stripped for doping violations – the most of any country, four times the number of the runner-up, and more than a third of the global total. From 2011 to 2015, more than a thousand Russian competitors in various sports, including summer, winter, and Paralympic sports, benefited from a cover-up.

Counter-jihad or Counterjihad or Counter-jihad movement is a political current loosely consisting of authors, bloggers, think tanks, street movements and campaign organisations all linked by a common belief that the Western world is being subjected to takeover by Muslims. Several academic accounts have presented conspiracy theory as a key component of the counter jihad movement.

While the roots of the movement go back to the 1980s, it did not gain significant momentum until after the September 11 attacks in 2001 and the 7 July 2005 London bombings. As far back as 2006, online commentators such as Fjordman were identified as playing a key role in forwarding the nascent counter-jihad ideology. The movement received considerable attention following the 2011 Breivik murders whose manifesto extensively reproduced the writings of prominent counter-jihad bloggers, and following the emergence of prominent street movements such as the English Defence League (EDL). The movement has been variously described as pro-Israel, anti-Islamic, Islamophobic, inciting hatred against Muslims, or far-right.

The movement has adherents both in Europe and in North America, which according to some vary in tone. The European wing is more focused on the alleged cultural threat to European traditions stemming from immigrant Muslim populations, whereas the American wing emphasizes an alleged external threat, essentially terrorist in nature.

Inert gas asphyxiation is a form of asphyxiation which results from breathing a physiologically inert gas in the absence of oxygen, or a low amount of oxygen, rather than atmospheric air (which is largely composed of nitrogen and oxygen). Examples of physiologically inert gases, which have caused accidental or deliberate death by this mechanism, are: argon, helium, nitrogen and methane. The term "physiologically inert" is used to indicate a gas which has no toxic or anesthetic properties and does not act upon the heart or hemoglobin. Instead, the gas acts as a simple diluent to reduce oxygen concentration in inspired gas and blood to dangerously low levels, thereby eventually depriving all cells in the body of oxygen.

According to the U.S. Chemical Safety and Hazard Investigation Board, in humans, "breathing an oxygen deficient atmosphere can have serious and immediate effects, including unconsciousness after only one or two breaths. The exposed person has no warning and cannot sense that the oxygen level is too low." In the US, at least 80 people died due to accidental nitrogen asphyxiation between 1992 and 2002. Hazards with inert gases and the risks of asphyxiation are well established.

An occasional cause of accidental death in humans, inert gas asphyxia with gases including helium, nitrogen, methane, and argon, has been used as a suicide method. Inert gas asphyxia has been advocated by proponents of euthanasia, using a gas-retaining plastic hood device colloquially referred to as a suicide bag.

Nitrogen asphyxiation has been suggested by a number of lawmakers and other advocates as a more humane way to carry out capital punishment. In April 2015, the Oklahoma Governor Mary Fallin signed a bill authorizing nitrogen asphyxiation as an alternative execution method in cases where the state's preferred method of lethal injection was not available as an option.

When humans breathe in an asphyxiant gas, such as pure nitrogen, helium, neon, argon, sulfur hexafluoride, methane, or any other physiologically inert gas(es), they exhale carbon dioxide without re-supplying oxygen. Physiologically inert gases (those that have no toxic effect, but merely dilute oxygen) are generally free of odor and taste. As such, the human subject detects little abnormal sensation as the oxygen level falls. This leads to asphyxiation (death from lack of oxygen) without the painful and traumatic feeling of suffocation (the hypercapnic alarm response, which in humans arises mostly from carbon dioxide levels rising), or the side effects of poisoning. In scuba diving rebreather accidents, there is often little sensation but euphoria—however, a slow decrease in oxygen breathing gas content has effects which are quite variable. By contrast, suddenly breathing pure inert gas causes oxygen levels in the blood to fall precipitously, and may lead to unconsciousness in only a few breaths, with no symptoms at all.

Some animal species are better equipped than humans to detect hypoxia, and these species are more uncomfortable in low-oxygen environments that result from inert gas exposure.

Counter-jihad is a transatlantic "radical right" wing movement which, via "the sharing of ideas between Europeans and Americans and daily linking between blogs and websites on both sides of the Atlantic" "calls for a counterjihad against the supposed Islamisation of Europe".

While the roots of the movement go back to the 1980s, it did not gain significant momentum until after the September 11 attacks in 2001.

The authors of "Right-Wing Populism in Europe: Politics and Discourse" describe the movement as heavily relying on two key tactics. "The first is arguing that the most radical Muslims – men like Osama bin Laden – are properly interpreting the Quran, while peaceful moderate Muslims either do not understand their own holy book or are strategically faking their moderation. The second key tactic is to relentlessly attack individuals and organizations that purport to represent moderate Islam...painting them as secret operatives in a grand Muslim scheme to destroy the West."

Benjamin Lee describes the "counter-jihad scene" as one where "Europe and the United States are under threat from an aggressive and politicized Islamic world that is attempting to take over Europe through a process of "Islamification" with the eventual aim of imposing Sharia law. In this process, the threat is characterized by the perceived removal of Christian or Jewish symbols, the imposition of Islamic traditions, and the creation of no-go areas for non-Muslims. The construction of mosques in particular is seen as continued reinforcement of the separation of the Muslim population from the wider populous. As strong as the threatening practices of Muslims in descriptions of the counter jihad are images of a powerless Europe in decline and sliding into decadence, unable to resist Islamic takeover. The idea that European culture in particular is in a state of decline, while a spiritually vigorous East represented by Islam is in the ascendancy in civil society, is a common sentiment in some circles."

Two central Counter-jihad themes have been identified:

- the notion that Islam poses a threat to "Western civilisation" with a particular focus on "Muslims living in Europe", that is, within the European Counterjihad Movement (ECJM), "seen predominantly in terms of immigration" particularly Muslim immigration.

- a lack of trust in regional, political and economic "elites", with a particular focus against the European Union (EU).

For much of his career, Lance Armstrong faced persistent allegations of doping, but until 2006 no official investigation was undertaken. The first break in the case came in 2004, when SCA Promotions, a Dallas-based insurer, balked at paying a $5 million bonus to Armstrong for winning his sixth consecutive Tour. SCA president Bob Hamman had read "L.A. Confidentiel", a book by cycling journalists Pierre Ballester and David Walsh which detailed circumstantial evidence of massive doping by Armstrong and members of his U.S. Postal Service Pro Cycling Team. In 2006, an arbitration panel ruled that SCA had to pay. However, Hamman's real goal was to force an investigation by sporting authorities. He believed that if someone in a position to investigate the matter found that Armstrong had indeed doped, he could be stripped of his Tour victories--allowing SCA to get its money back. His hunch proved correct; officials from the United States Anti-Doping Agency (USADA) asked to review the evidence Hamman had gleaned.

According to British journalist Andrew Jennings, a KGB colonel stated that the agency's officers had posed as anti-doping authorities from the International Olympic Committee to undermine doping tests and that Soviet athletes were "rescued with [these] tremendous efforts". On the topic of the 1980 Summer Olympics, a 1989 Australian study said "There is hardly a medal winner at the Moscow Games, certainly not a gold medal winner, who is not on one sort of drug or another: usually several kinds. The Moscow Games might as well have been called the Chemists' Games."

Documents obtained in 2016 revealed the Soviet Union's plans for a statewide doping system in track and field in preparation for the 1984 Summer Olympics in Los Angeles. Dated prior to the country's decision to boycott the Games, the document detailed the existing steroids operations of the program, along with suggestions for further enhancements. The communication, directed to the Soviet Union's head of track and field, was prepared by Dr. Sergei Portugalov of the Institute for Physical Culture. Portugalov was also one of the main figures involved in the implementation of the Russian doping program prior to the 2016 Summer Olympics.
