Dissociative Fugue

A person in a Dissociative Fugue adopts a new identity after leaving their previous living arrangements and forgetting or being confused about their previous identity. They are able to perform well enough to survive under the new identity. These episodes are generally are caused by a severe stressor and are time limited to a few days, but may last up to months. When the fugue ends, the person is unable to recall what occurred during this state.

Dissociative Amnesia

In Dissociative Amnesia, the person is unable to remember personal information. They are aware that they have forgotten information, but do not know what they have forgotten. While they are able to perform simple tasks, they usually are unable to perform more complex ones such as shopping and cooking, instead wandering aimlessly. This type of amnesia usually lasts for a period of hours to days follows a severe stressor, and may be selective for a traumatic event.

Depression

Major Depression affects 15% of Americans at some point during their lives, and 100 million people are affected on any given day. The age of onset is fairly evenly spread among people. The mean age is 40, but Depression can onset from childhood to seniors. It can come on suddenly in days, or build over years. Anxiety, phobias, panic and Dysthymia can predate it. On average, the course of Major Depression runs 3 to 9 months if untreated, and 85% cases resolve within 1 year. Over 1/2 of people who experience major depression only have one episode. With each successive episode, the patient has a 15% risk that their next episode will be a manic episode, changing their diagnosis to Bipolar Disorder. In the end, approximately 15-20% of those with major depression become chronically depressed. Approximately 15% of patients with major depression may commit suicide, as well, with men committing suicide at a rate 2 times as often as women.

Depersonalization Disorder

Depersonalization Disorder is where a person "looks at themselves from the outside", and observes their own physical actions or mental processes as if they were an observer instead of themselves. This often brings a sense of unreality, and an alteration in the perception of the environment around them, as well as the person fearing they are not in full control of themselves. Depersonalization can occur during a number of different times, and not be a disorder. In order to qualify as a disorder, it must be recurrent to the point that it interferes with daily functioning in at least one major area of life.

Dependent Personality Disorder

Dependent Personality Disorder is manifested via passively allowing others to assume responsibility for major areas of ones life due to lack of self-confidence or lack of ability to function independently. This leads to the person making their own needs secondary to the needs of others, and then becoming dependent on them. While everyone is dependent on others for some parts of their lives, those with dependent personality disorder are dependent on almost all major areas of their lives, and view themselves poorly, and good only as extensions of others.

Dementia an overveiw

Dementia is categorized as being caused by four subtypes: Alzheimer's disease (the most common subtype, accounting for 50% of dementias); Vascular reasons (such as a stroke or hypertension, accounting for 9-15% of dementias); Substance abuse persisting dementias (accounting for 7-9% of dementias, with alcohol the major cause of most of these; and General medical conditions such as Parkinson's disease, Huntington disease, and other neurological illnesses (accounting for 20-30%). Psuedodementia can also be caused by other mental illnesses such as Major Depressive Disorder and Psychosis. Regardless of the cause, the dementias all have common factors. Initially in dementia, there is memory loss for recent events such as stoves being left on, keys being misplaced, conversations forgotten. Later, people begin to get lost while driving roads that they once knew very well, and questions must be repeated because the questions and answers are quickly forgotten. The long-ago memories are retained and dwelled upon. Personality changes occur, and the person may manifest changes that are the complete opposite from their previous personality. Poor judgment and impulse control often go hand-in-hand. They may speak crudely, make lewd gestures and display their genitals.

Delusional Disorder

There is not a single type of Delusional Disorder. There are a number of subtypes, but they share a major common feature. This is that the person has a nonbizzare delusion - a delusion that could occur in real life, that is. For example, a person that feels they are being followed or poisoned is nonbizarre, while a person who feels their parents are from mars is bizarre. The subtypes are erotomanic, in which the person believes that a person of usually higher status is in love with them; grandiose, which is delusions of inflated worth, power, knowledge, identity, or special relationships; jealous is that where they believe the sexual partner is unfaithful; persecutory by which they believe they or someone they are close to is being maltreated; somatic, in which they believe they have a physical problem, defect, or illness; or, the mixed type, in which more than one of the previous types is present.

Delerium a Disorder

Delirium is a state where there is a shadowing of consciousness, disorientation and loss of recent memmory.The onset is quick (hours to day) and the symptoms may worsen as the day goes on, which is know as “sundowners syndrome”. This maybe caused by a medical condition, substance use, substance withdrawal, or medical side effects.

Cyclothymic Disorder

Cyclothemia is a mood disorder in which the client displays the characteristic ups and downs (depression and euphoria) of Bipolar Disorder, to a much lower extent, and does not qualify for a diagnosis of Bipolar Disorder. These symptoms must last for a period of at least two years, with no period longer than 2 months in which they have been at a normal state, and no mixed episodes may have occurred.

Conversion Disorder

Conversion Disorder is a psychologically caused alteration or loss of physical function, such as blindness or paralysis. This alteration often has significance psychologically to the patient, even if they are unaware of it, and can persist for years.

Conduct Disorder

Conduct Disorder is essentially a disorder where the person violates the social norms and rights of others. Those with this disorder are habitually in trouble, either with parents, teachers or peers. Despite presenting a tough image to those around them, they have a low self-esteem. Their frustration tolerance, irritability, temper outbursts and recklessness are hallmarks. Conduct Disorder may lead to adult antisocial personality disorder.

Cognitive Disorder NOS

Cognitive Disorder NOS (not otherwise specified) is diagnosed when a patient has a syndrome of cognitive impairment that does not meet the criteria for delerium, dementia or amnestic disorders. They are often due to a specific medical condition and/or a pharmacological reaction.

Childhood Disorder NOS

This diagnosis is used for disorders with onset in infancy, childhood, or adolescence that do not meet the criteria for any specific disorder. According to the ICD-10, there are two sub-categories: 1) Other specified behavioral and emotional disorders usually occurring during in childhood and adolescence and 2) Unspecified behavioral and emotional disorders with onset usually occurring in childhood and adolescence.

Childhood Disintegrative Disorder

Childhood disintegrative disorder is a condition in which children develop normally until age 3 or 4, but then demonstrate a severe loss of social, communication and other skills.

Doctors sometimes confuse this disorder with late-onset autism. Both conditions involve normal development followed by significant loss of language, social, play and motor skills. Childhood disintegrative disorder and autism are among several disorders known as pervasive developmental disorders or autism spectrum disorders.

Autism typically occurs at an earlier age than childhood disintegrative disorder. There's also a more dramatic loss of skills with childhood disintegrative disorder and a greater likelihood of mental retardation. In addition, childhood disintegrative disorder is far less common than autism.

Treatment for childhood disintegrative disorder involves a combination of medications, behavior therapy and other approaches.
Symptoms

Children with childhood disintegrative disorder typically show the following signs and symptoms:

Normal development for at least the first two years of life
This includes normal development of age-appropriate verbal and nonverbal communication, social relationships, and motor, play and self-care skills.

Significant loss of previously acquired or learned skills
This loss occurs before age 10, in at least two of the following areas:
Ability to say words or sentences (expressive language)
Ability to understand verbal and nonverbal communication (receptive language)
Social skills and self-care skills (adaptive behavior)
Bowel and bladder control
Play skills
Motor skills (ability to voluntarily move the body in a purposeful way)

Lack of normal function or impairment
This lack or impairment occurs in at least two of the following areas:
Social interaction. This may include impairment in nonverbal behaviors, failure to develop peer relationships, and lack of social or emotional reciprocity — an inability to share, recognize, understand and respond to social cues and interactions or to feelings of others.
Communication. This may include delay or lack of spoken language, inability to initiate or sustain a conversation, stereotyped and repetitive use of language, and lack of varied imaginative or make-believe play.
Repetitive and stereotyped patterns of behavior, interests and activities. This may include hand flapping, rocking, spinning (motor stereotypes and mannerisms); development of specific routines and rituals; difficulty with transitions or changes in routine; maintaining a fixed posture or body position (catatonia); and preoccupation with certain objects or activities.

Loss of developmental milestones may occur abruptly over the course of days to weeks or gradually over an extended period of time.

Bulimia Nervosa disorder


Bulimia Nervosa is a pattern of binge eating and purging, in which the bulimic view themselves as unable to control their eating, and feel guilty and angry after binging. Nearly 90% of bulimics engage in self-induced vomiting after binging, although this is not a requirement for a person to be diagnosed with this disorder. They can also be diagnosed if they engage in any inappropriate weight control method such as misuse of laxatives, taking diuretics, fasting, use of enemas, or excessive exercise. Bulimics, through binging or weight control measures, can vary their body weight up to 10 pounds per day.

Brief Psychotic Disorder

Brief Psychotic Disorder is a psychosis that has a rapid onset, generally following a major stressor. Its hallmark is emotional turmoil, mood lability, and confusion. The sufferer must have one of the following symptoms, delusion, hallucinations, grossly disorganized or catatonic behavior or disorganized speech. A brief psychotic episode is time limited, lasting at least a day, but less than a month. As a rule the quicker the onset, the faster the recovery

Breathing-Related Sleep Disorder


Breathing-Related Sleep Disorder, also known as sleep apnea, causes the sufferer to stop breathing during the night for periods lasting from 30 seconds to 2 minutes, upto 400 times per night. The sufferers are divided into two groups 1) The 2/3 who feels exhausted by day and 2)1/3 who cannot fall asleep at night. Often this associated with people who are overweight, suffer from coronary artery disease or have had strokes

Borderline Personality Disorder

Borderline Personality Disorder (BPD) occurs in approximately 2% of the population. It is a disorder in which a person has a pattern of unstable personal relationships, a self-image that is not well formed, and poor impulse control in areas such as spending, sexual conduct, driving, eating, and substance abuse. Additionally, the person suffering from BPD fears abandonment and will go to any length to prevent this. They feel chronic emptiness.
One of the hallmarks of BPD is known as "splitting". This is where the person with BPD will swing between idealizing and devaluing people in relationships. They will pit people against one another, making one group the "white hats" and the other the "black hats". A person is either good or bad, the person with BPD being unable to reconcile that there is both good and bad within a person. And this categorization of a person may shift from day to day, the person being good one day and bad the next.
There may be suicidal threats, gestures or attempts made by the person with BPD. There may also be self-mutilation that occurs. Their mood may be very prone to outside stress, with feelings of depression and anger readily provoked, with anxiety also a common occurrence. With extreme stress, the person with BPD may experience paranoid ideation, or may have dissociative symptoms such as "running on automatic" and disconnecting from reality.
The treatment for BPD may consist of medication and therapy. Antidepressants may help with depression while specific SSRI's (prozac, zoloft, etc) may help with impulse control. Mood stabilizers (antiepileptics such as tegretol, depakote) can help with mood swings and irritability. Cognitive Behavioral Therapy, and the related Dialectical Behavior Therapy are the two most common therapies used in the treatment of BPD.

Body Dysmorphic Disorder


Body Dysmorphic Disorder occurs in people who are normal-looking.However,they are overly concerned with a small defect in their apperance.In order to qualify for this diagnosis,this preoccupation must affect their lives in at least one situation,be it work,leisure or marriage,or couse significant distress.Oftentimes those with this disorder may go so far as to have a plastic surgery

Bipolar Disorder


Bipolar disorder also known as manic depression is an affective disorder that causes periodic mood swings in which they cycle from depression to mania. Depression may be characterized by having a lack of motivation, difficulty doing tasks, short attention span, decreased appetite, crying spells, difficulty in getting to sleep or sleeping too much, and in the more severe cases thoughts of self harm. Mania is separated into two types: Full mania and hypomania. Mania may be characterized by a decreased need for sleep, decreased self-control, overspending, increased sexual activity, irritability, rage, risk-taking behaviors, and in the more severe cases psychotic states. Hypomania is described as having the same behaviors, to a less extreme level.

Binge Eating Disorder


A binge is defined as eating in a discrete period of time (a limited period, usually less than two hours) an amount of food that is definitely larger than most individuals would eat under similar circumstances. A binge is not limited to a single sitting and typically includes sweet, high caloric foods and is characterized more by abnormality in the amount of food consumed than by a craving for a specific nutrient such as carbohydrates.

Avoidant Personality Disorder


Avoidant Personality Disorder is where a person has an extreme fear of being judged negatively by other people, and suffers from a high level of social discomfort as a result. They tend to only enter into relationships where uncritical acceptance is almost guranteed.They undergo social withdrawal, suffer from low self-esteem, but have a great desire of affection and acceptance.However,they do not want the affection as they fear the rejection

Autism an mental ileness among infants


Autism may manifest in early infancy, with the infant shying away from the parents touch, not responding to a parent who returns after an absence, and inappropriate gaze behaviour.The Autistic child may fail to meet early language and other development milestones. And there can be as much as 3-year delay between the report of symptoms and the diagnosis, which is usually made at around the age five. The disorder occurs in boys three to four times more often than in girls.

Attention Deficit Hyperactivity Disorder


Attention Deficit Hyperactivity Disorder sometimes inaccurately referred to as ADD (there is no clinical term by this name) is a disorder usually first diagnosed in infancy, childhood or adolescence. There are 4 recognized types of ADHD.They are:-1) Predominantly Inattentive type, 2) Predominantly Hyper Active-Impulsive type, 3) Combined type and 4) ADHD.There is a high level of correlation with children with ADHD and other psychiatric illnesses. This includes illness ranging from behavioral, mood, family, anxiety, cognitive, social to school functioning, with the greatest increase in those with ADHD-combines subtype

Asperger's Syndrome over veiw



Asperger’s disorder is a separate Autistic Spectrum disorder which does not meet criteria for other Pervasive Developmental Disorders or Schizophrenia. Features of this disease are severe and sustained impairment in social interaction and the development of repetitive patters of behaviour, interests and activities and significant impairment in social, occupational and other important areas of functioning. Because there are no significant language delays or cognitive deflects, Asperger’s is considered as a form of highly functioning autism

Anxiety Disorder study


Anxiety Disorder is diagnosed when patients have symptoms of anxiety disorder or adjustment disorder with anxiety disorder or mixed anxiety and depressed mood.The category generally includes patients disorders with prominent anxiety or phobiac avoidance that do not meet criterai for any specific anxiety disporder,adjustment disorder with anxiety,or adjustemt disorder with mixed anxiety and depressed mood

Antisocial Personality Disorder an Over veiw

Antisocial Personality Disorder results in what is commonly known as a Sociopath. The numbers of persons with this disorder are much higher than generally thought, with nearly 6% of men and over 1% of women having this disorder. The criteria for this disorder require an ongoing disregard for the rights of others, since the age of 15 years. Some examples of this disregard are reckless disregard for the safety of themselves or others, failure to conform to social norms with respect to lawful behaviors, deceitfulness such as repeated lying or deceit for personal profit or pleasure, and lack of remorse for actions that hurt other people in any way. Additionally, they must have evidenced a Conduct Disorder before the age of 15 years, and must be at least 18 years old to receive this diagnosis.

People with this disorder appear to be charming at times, and make relationships, but to them, these are relationships in name only. They are ended whenever necessary or when it suits them, and the relationships are without depth or meaning, including marriages. They seem to have an innate ability to find the weakness in people, and are ready to use these weaknesses to their own ends through deceit, manipulation, or intimidation, and gain pleasure from doing so.

They appear to be incapable of any true emotions, from love to shame to guilt. They are quick to anger, but just as quick to let it go, without holding grudges. No matter what emotion they state they have, it has no bearing on their future actions or attitudes.

The rarely are able to have jobs that last for any length of time, as they become easily bored, instead needing constant change. They live for the moment, forgetting the past, and not planning the future, not thinking ahead what consequences their actions will have. They want immediate rewards and gratification.

Treating antisocial personality disorder can be difficult as those with this disorder may have little or no desire to change themselves, which is a prerequisite. No medication is available either. Appropriate treatments for antisocial personality disorder include group psychotherapy, having feedback from peers, and constructive confrontation of inappropriate behaviors.
