Demonophobia (or daemonophobia) is a fear of demons, a type of specific phobia. It was first described in 13th century and common in the sixteenth century but has since largely disappeared.

Panphobia, omniphobia, pantophobia, or panophobia is a vague and persistent dread of some unknown evil. Panphobia is not registered as a type of phobia in medical references.

Most phobias are classified into three categories and, according to the "Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition" (DSM-V), such phobias are considered to be sub-types of anxiety disorder. The categories are:

1. Specific phobias: Fear of particular objects or social situations that immediately results in anxiety and can sometimes lead to panic attacks. Specific phobia may be further subdivided into five categories: animal type, natural environment type, situational type, blood-injection-injury type, and other.

2. Agoraphobia: a generalized fear of leaving home or a small familiar 'safe' area, and of possible panic attacks that might follow. It may also be caused by various specific phobias such as fear of open spaces, social embarrassment (social agoraphobia), fear of contamination (fear of germs, possibly complicated by obsessive-compulsive disorder) or PTSD (post traumatic stress disorder) related to a trauma that occurred out of doors.

3. Social phobia, also known as social anxiety disorder, is when the situation is feared as the person is worried about others judging them.

Phobias vary in severity among individuals. Some individuals can simply avoid the subject of their fear and suffer relatively mild anxiety over that fear. Others suffer full-fledged panic attacks with all the associated disabling symptoms. Most individuals understand that they are suffering from an irrational fear, but are powerless to override their panic reaction. These individuals often report dizziness, loss of bladder or bowel control, tachypnea, feelings of pain, and shortness of breath.

The following symptoms can be exhibited when a person suffering from equinophobia either thinks of a horse or is physically near one:

- Feeling of terror

- Anxiety (even if the horse is calm)

- Trembling

- Panic

- Palpitations

- Shortness of breath

- Sudden increase in pulse rate

- Nausea

- Crying

Sufferers of equinophobia may also fear other hoofed animals such as donkeys, mules, and ponies.

There is no specific phobia in the DSM-5 which provides criteria for an all-encompassing fear of everything, though the defining symptom for Generalized Anxiety Disorder in this manual is "excessive anxiety and worry (apprehensive expectation) about a number of events or activities." Another very relatable state of mind is paranoia, in which one fears that unknown threats could, and most likely will, come from anyone, with distrust potentially leading to a loss of touch with reality. Delusional disorder is a more severe form of this type of disorder. Relevant academic literature may point to panphobia as merely a piece of such more complex states of mental disorder. Pseudoneurotic schizophrenia may be diagnosable in patients who, in addition to panphobia, also exhibit symptoms of "pananxiety", "panambivalence", and to a lesser extent, "chaotic sexuality". These persons differ from generalized anxiety sufferers in that they have "free-floating anxiety that rarely subsides" and are clinically diagnosable as having borderline personality disorder in the DSM-IV-TR. No significant changes related to this personality disorder were made in transitioning to the DSM-5, suggesting the diagnostic criteria are still appropriate.

The symptoms of Ablutophobia as well as many specific phobias are as follows:

- Feelings of panic, dread, horror, or terror

- Recognition that the fear goes beyond normal boundaries and the actual threat of danger

- Reactions that are automatic and uncontrollable, practically taking over the person’s thoughts

- Rapid heartbeat, shortness of breath, trembling, and an overwhelming desire to flee the situation—all the physical reactions associated with extreme fear

- Extreme measures taken to avoid the feared object or situation.

Feelings of shame are also not uncommon. Many cultures place a heavy value on cleanliness, and refusing to bathe can make someone the target of mockery or teasing, which can increase the severity of the phobia. It may also cause the sufferer to not seek treatment.

Individuals with scopophobia generally exhibit symptoms in social situations when attention is brought upon them like public speaking. Several other triggers exist to cause social anxiety. Some examples include: Being introduced to new people, being teased and/or criticized, embarrassing easily, and even answering a cell phone call in public.

Often scopophobia will result in symptoms common with other anxiety disorders. The symptoms of scopophobia include an irrational feelings of panic, feelings of terror, feelings of dread, rapid heartbeat, shortness of breath, nausea, dry mouth, trembling, anxiety and avoidance. Other symptoms related to scopophobia may be hyperventilation, muscle tension, dizziness, uncontrollable shaking or trembling, excessive eye watering and redness of the eyes.

The "DSM-IV-TR" provides the following criteria for the diagnosis of a specific phobia:

The book "Phobias" defines a panic attack as "a sudden terror lasting at least a few minutes with typical manifestations of intense fear". These manifestations may include palpitations, sweating, trembling, difficulty breathing, the urge to escape, faintness or dizziness, dry mouth, nausea and/or several other symptoms. As with other specific phobias, patients suffering from cynophobia may display a wide range of these reactions when confronted with a live dog or even when thinking about or presented with an image (static or filmed) of a dog. Furthermore, classic avoidance behavior is also common and may include staying away from areas where dogs might be (i.e., a park), crossing the street to avoid a dog, or avoiding the homes of friends and/or family who own a dog.

Emetophobia is a phobia that causes overwhelming, intense anxiety pertaining to vomiting. This specific phobia can also include subcategories of what causes the anxiety, including a fear of vomiting in public, a fear of seeing vomit, a fear of watching the action of vomiting or fear of being nauseated. It is common for emetophobics to be underweight, or even anorexic, due to strict diets and restrictions they make for themselves. The thought of someone possibly vomiting can cause the phobic person to engage in extreme behaviors to escape the perceived (and sometimes very real) threat of that particular situation, in which the phobic person will go to great lengths to avoid even potential situations that could even be perceived as "threatening".

Emetophobia is clinically considered an "elusive predicament" because limited research has been done pertaining to it. The fear of vomiting receives little attention compared with other irrational fears. Emetophobia is not limited by age or maturity level. There are cases of emetophobia present in childhood and adolescence, as well as adulthood.

The event of vomiting may scare away anyone with this peculiar phobia. Some may fear someone throwing up while another may fear themselves throwing up. Some may have both.

Some may have anxiety which makes them feel like they will throw up when it actually might not. People with Emetophobia usually suffer from anxiety, they often scream or cry when someone or something has been sick.

The symptoms of autophobia vary by case. However, there are some symptoms that a multitude of people with this disease suffer from. An intense amount of apprehension and anxiety when you are alone or think about situations where you would be secluded is one of the most common indications that a person is autophobic. People with this disorder also commonly believe that there is an impending disaster waiting to occur whenever they are left alone. For this reason, autophobes go to extreme lengths to avoid being in isolation. However, people with this disease often do not need to be in "physical" isolation to feel abandoned. Autophobes will often be in a crowded area or group of people and feel as though they are completely secluded.

There has also been some connection to autophobia being diagnosed in people who also suffer from borderline personality disorders.

Below is a list of other symptoms that are sometimes associated with autophobia:

- Mental symptoms:

- Fear of fainting

- A disability to concentrate on anything other than the disease

- Fear of losing your mind

- Failure to think clearly

- Emotional symptoms:

- Stress over up-coming times and places where you may be alone

- Fear of being secluded

- Physical symptoms:

- Lightheadedness, dizziness

- Sweating

- Shaking

- Nausea

- Cold and hot flashes

- Numbness or tingling feelings

- Dry mouth

- Increased heart rate

Entomophobia (also known as insectophobia) is a specific phobia characterized by an excessive or unrealistic fear of one or more classes of insect, and classified as a phobia by the DSM-5. More specific cases included apiphobia (fear of bees) and myrmecophobia (fear of ants). One book claims 6% of all US inhabitants suffer from it.

Entomophobia may develop after the person has had a traumatic experience with the insect(s) in question. It may develop early or later in life and is quite common among the animal phobias. Typically one suffers from a fear from one specific type of insect, and entomophobia leads to behavioral changes: the sufferer will avoid situations where they may encounter the specific type of insect. Cognitive behavioral therapy is considered an effective treatment.

The root word for emetophobia is "emesis", from the Greek word "emein" which means "an act or instance of vomiting" with "-phobia” meaning "an exaggerated usually inexplicable fear of a particular object, class of objects, or situation."

People with emetophobia frequently report a vomit related traumatic event, such as a long bout of stomach flu, accidentally vomiting in public, or having to witness someone else vomit, as the start of the emetophobia. They may also be afraid of hearing that someone is feeling like vomiting or that someone has vomited, usually in conjunction with the fears of seeing someone vomit or seeing vomit.

Herpetophobia is a common specific phobia, which consists of fear or aversion to reptiles, commonly lizards and snakes, and similar vertebrates as amphibians. It is one of the most diffused animal phobias, very similar and related to ophidiophobia. This condition causes a slight to severe emotional reaction, as for example anxiety, panic attack or most commonly nausea.

Phobophobia is mainly linked with internal predispositions. It is developed by the unconscious mind which is linked to an event in which phobia was experienced with emotional trauma and stress, which are closely linked to anxiety disorders and by forgetting and recalling the initiating trauma. Phobophobia might develop from other phobias, in which the intense anxiety and panic caused by the phobia might lead to fearing the phobia itself, which triggers phobophobia before actually experiencing the other phobia. The extreme fear towards the other phobia can lead the patient to believe that their condition may develop into something worse, intensifying the effects of the other phobia by fearing it. Also, phobophobia can be developed when anxiety disorders are not treated, creating an extreme predisposition to other phobias. The development of phobophobia can also be attributed to characteristics of the patient itself, such as phylogenetic influence, the prepotency of certain stimuli, individual genetic inheritance, age incidence, sex incidence, personality background, cultural influence inside and outside the family, physiological variables and biochemical factors.

Phobophobia shares the symptoms of many other anxiety disorders, more specifically panic attacks and generalized anxiety disorder:

1. Dizziness

2. Heart pounding

3. An excess of perspiration

4. Slight paresthesia

5. Tension

6. Hyperventilation

7. Angst

8. Faintness

9. Avoidance

In 2009, a study investigated the impact of anthropophobia in specific cultures. 50 patients diagnosed with anthropophobia, 50 patients diagnosed with neurasthenia, and 50 control subjects were recruited from hospitals in Beijing, China. Measures of anthropophobic and anxiety symptoms were administered to the subjects. The patients with anthropophobia could not even make eye contact with others and were afraid of being watched. The conclusion drawn was that anthropophobics, like neurasthenics, experience anxiety and depression, but "more cognitively and less somatically".

Anthropophobia or Anthrophobia (literally "fear of humans", from , "ánthropos", "human" and , "phóbos", "fear"), also called interpersonal relation phobia or social phobia, is pathological fear of people or human company.

Anthropophobia is an extreme, pathological form of shyness and timidity. Being a form of social phobia, it may manifest as fears of blushing or meeting others' gaze, awkwardness and uneasiness when appearing in society, etc. A specific Japanese cultural form is known as taijin kyofusho.

Anthropophobia can be best defined as the fear of people in crowded situations, but can also go beyond and leave the person uncomfortable when being around just one person. Conditions vary depending on the person. Some cases are mild and can be handled while more serious cases can lead to complete social withdrawal and the exclusive use of written and electronic communication.

Workplace phobia is an anxiety disorder and specific phobia associated with workspace.

A person with astraphobia will often feel anxious during a thunderstorm even when they understand that the threat to them is minimal. Some symptoms are those accompanied with many phobias, such as trembling, crying, sweating, panicked reactions, the sudden feeling of using the bathroom, nausea, the feeling of dread, fingers in the ears and rapid heartbeat. However, there are some reactions that are unique to astraphobia. For instance, reassurance from other people is usually sought, and symptoms worsen when alone. Many people who have astraphobia will look for extra shelter from the storm. They might hide underneath a bed, under the covers, in a closet, in a basement, or any other space where they feel safer. Efforts are usually made to smother the sound of the thunder; the person may cover their ears or curtain the windows.

A sign that someone has astraphobia is a very heightened interest in weather forecasts. An astraphobic person will be alert for news of incoming storms. They may watch the weather on television constantly during rainy bouts and may even track thunderstorms online. This can become severe enough that the person may not go outside without checking the weather first. In very extreme cases, astraphobia can lead to agoraphobia, the fear of leaving the home.

Physical symptoms include dry mouth, tremors, tightening in the chest, rapid breathing, sweating of the palms, nausea and irregular heart beat.

Phobophobia is the fear of phobia(s) and, more specifically, of the internal sensations associated with that phobia and anxiety, which binds it closely to other anxiety disorders, especially with generalized anxiety disorders (free floating fears) and panic attacks. It is a condition in which anxiety disorders are maintained in an extended way, which combined with the psychological fear generated by phobophobia of encountering the feared phobia would ultimately lead to the intensifying of the effects of the feared phobia that the patient might have developed, such as agoraphobia, and specially with it, and making them susceptible to having an extreme fear of panicking. Phobophobia comes in between the stress the patient might be experiencing and the phobia that the patient has developed as well as the effects on his life, or in other words, it is a bridge between anxiety/panic the patient might be experiencing and the type of phobia he/she fears, creating an intense and extreme predisposition to the feared phobia. Nevertheless, phobophobia is not necessarily developed as part of other phobias, but can be an important factor for maintaining them.

Phobophobia differentiates itself from other kind of phobias by the fact that there is no environmental stimulus per se, but rather internal dreadful sensations similar to psychological symptoms of panic attacks. The psychological state of the mind creates an anxious response that has itself a conditioned stimuli leading to further anxiety, resulting in a vicious cycle. Phobophobia is a fear experienced before actually experiencing the fear of the feared phobias its somatic sensations that precede it, which is preceded by generalized anxiety disorders and can generate panic attacks. Like all the phobias, the patients avoids the feared phobia in order to avoid the fear of it.

Cynophobia (from the "kýōn" "dog" and "phóbos" "fear") is the fear of dogs. Cynophobia is classified as a specific phobia, under the subtype "animal phobias". According to Dr. Timothy O. Rentz of the Laboratory for the Study of Anxiety Disorders at the University of Texas, animal phobias are among the most common of the specific phobias and 36% of patients who seek treatment report being afraid of dogs or cats. Although snakes and spiders are more common animal phobias, cynophobia is especially debilitating because of the high prevalence of dogs (for example, there are an estimated 25 million stray dogs in India, and an estimated 62 million pet dogs in the United States) and the general ignorance of dog owners to the phobia. The "Diagnostic and Statistical Manual of Mental Disorders" ("DSM-IV-TR") reports that only 12% to 30% of those suffering from a specific phobia will seek treatment.

A phobia is a type of anxiety disorder, defined by a persistent fear of an object or situation. The phobia typically results in a rapid onset of fear and is present for more than six months. The affected person will go to great lengths to avoid the situation or object, typically to a degree greater than the actual danger posed. If the feared object or situation cannot be avoided, the affected person will have significant distress. With blood or injury phobia, fainting may occur. Agoraphobia is often associated with panic attacks. Usually a person has phobias to a number of objects or situations.

Phobias can be divided into specific phobias, social phobia, and agoraphobia. Types of specific phobias include those to certain animals, natural environment situations, blood or injury, and specific situations. The most common are fear of spiders, fear of snakes, and fear of heights. Occasionally they are triggered by a negative experience with the object or situation. Social phobia is when the situation is feared as the person is worried about others judging them. Agoraphobia is when fear of a situation occurs because it is felt that escape would not be possible.

Specific phobias should be treated with exposure therapy where the person is introduced to the situation or object in question until the fear resolves. Medications are not useful in this type of phobia. Social phobia and agoraphobia are often treated with some combination of counselling and medication. Medications used include antidepressants, benzodiazepines, or beta-blockers.

Specific phobias affect about 6–8% of people in the Western world and 2–4% of people in Asia, Africa, and Latin America in a given year. Social phobia affects about 7% of people in the United States and 0.5–2.5% of people in the rest of the world. Agoraphobia affects about 1.7% of people. Women are affected about twice as often as men. Typically onset is around the age of 10 to 17. Rates become lower as people get older. People with phobias are at a higher risk of suicide.

Helminthophobia, scoleciphobia or vermiphobia is a specific phobia, the fear of worms, especially parasitic worms. The sight of a worm, or anything that looks like a worm, may cause someone with this phobia to have extreme anxiety or even panic attacks.

A variety of symptoms can be seen in someone suffering from telephone phobia, many of which are shared with anxiety. These symptoms may include nervous stomach, sweaty palms, rapid heartbeat, shortness of breath, nausea, dry mouth and trembling. The sufferer may experience feelings of panic, terror and dread. Resulting panic attacks can include hyperventilation and stress. These negative and agitating symptoms can be produced by both the thought of making and receiving calls and the action of doing so.

A specific phobia is any kind of anxiety disorder that amounts to an unreasonable or irrational fear related to exposure to specific objects or situations. As a result, the affected person tends to avoid contact with the objects or situations and, in severe cases, any mention or depiction of them. The fear can, in fact, be disabling to their daily lives.

The fear or anxiety may be triggered both by the presence and the anticipation of the specific object or situation. A person who encounters that of which they are phobic will often show signs of fear or express discomfort. In some cases, it can result in a panic attack. In most adults, the person may logically know the fear is unreasonable but still find it difficult to control the anxiety. Thus, this condition may significantly impair the person's functioning and even physical health.

Specific phobia affects up to 12% of people at some point in their life.
