Unplanned behavior

Introduction The so-called personality disorder refers to a serious personality defect that develops in childhood or adolescence, or a type of mental abnormality in which personality is generally unsuitable. Personality disorder leads to failure to adapt to normal social life, manifested as obstacles in emotion and will, but there is no abnormality in thinking and intelligence, and the consciousness is clear. The personality defects of such people are persistent and stubborn, and most of them continue into adulthood, and even life cannot be changed. The behavior of patients with ruthless personality disorder is mostly driven by accidental motivation, emotional impulses or instinctive desires, lack of planning or premeditated. Antisocial personality disorder, also known as ruthless personality disorder, is one of the most harmful to society.

Cause

The etiology and pathogenesis of morbid personality or antisocial personality disorder have not yet been elucidated. The following are relevant information:

1. Inheritance: The incidence of this disease in relatives is positively related to blood relationship, that is, the closer the blood relationship is, the higher the incidence rate. There is data showing that the abnormal EEG rate of the parents is higher; the homozygosity of single-oval twins is higher, the EEG is similar, and the crime rate is higher than that of twins. Compared with the normal control group, the foster children of morbid personality have a higher incidence of morbid personality.

2, brain dysplasia: EEG examination confirmed that this type of personality patients with immature brain development, may have brain damage. From the pathological psychology analysis, the patient's psychological behavior is naive, very immature, and is a pathological change of immature personality.

3. Family and social environment: Many surveys have shown that childhood trauma, unfamiliar family relationships, bad family education methods and bad social and environmental factors also play an important role in the pathogenesis. It is a well-established fact that human personality formation has great plasticity, especially in infants and children.

This type of personality disorder often manifests as follows:

1. Highly aggressive: Patients with high levels of impulsivity and aggression are well known, while others have no aggressive behavior. Antisocial personality can be divided into two types: aggressive behavior and non-dominant. The former has a tendency to have personal violence throughout life.

2, no shame: Traditionally, such people are not ashamed and lack of autonomic responses related to anxiety (including skin DC response).

3, behavioral unplanned: the behavior of patients with ruthless personality disorder is mostly driven by accidental motivation, emotional impulses or instinctive desires, lack of planning or premeditated.

4, social maladaptation: maladaptation is an important feature of such personality disorder patients. Because of the lack of self-awareness of one's personality defects and the inability to learn from experience, this disease is a persistent and strong pattern of maladaptive behavior.

Differential diagnosis

Behavioral disorders and peculiarity are one of the clinical manifestations of mental disorders associated with intracranial tumors. A mental disorder associated with an intracranial tumor refers to an intracranial tumor that invades the brain tissue or cerebral blood vessels of the brain parenchyma, causing damage to the brain parenchyma or increased intracranial pressure. Patients suffering from intracranial tumors have 40% to 100% of people can have mental symptoms.

(1) Somatic symptoms: headache, nausea and vomiting, optic disc edema and vision loss are the three main manifestations of increased intracranial pressure caused by brain tumors. Increased intracranial pressure occurs in approximately 80% of patients with intracranial tumors due to brain tumor expansion. 1 headache. 2 vomiting. 3 optic disc edema. Approximately one-third of patients with brain tumors often develop seizures. Increased intracranial pressure may also have convulsions, poor balance in standing position, tenderness in the trigeminal nerve distribution area, nerve palsy, diplopia, dizziness, tripping and so on. In acute or subacute cases, there are still pulse, blood pressure and respiratory changes. The pulse can be slowed down to between 50 and 60 beats per minute, and the breathing slows and becomes deeper. When the intracranial pressure continues to increase, the pulse can be increased and irregular.

(2) Psychiatric symptoms: The general psychiatric symptoms of intracranial tumors include confusion, amnesia syndrome, dementia, and less common sputum-like and schizophrenia-like psychosis.

Suicidal behavior: Suicide is the behavior of an individual who intentionally or voluntarily adopts various means to end his or her life. Suicide does not happen suddenly, it has a process of development. Japanese scholar Nagaoka pointed out that the suicide process generally experienced: suicidal ideation - committing suicide - behavior change + thinking about suicide - choosing the location and time of suicide - taking suicidal behavior. For people of different ages, different personalities, and different situations, the suicide process is long and short.

Impulsive behavior: An act that occurs suddenly and often causes adverse consequences; a violent behavior is an act that intentionally causes damage to property or other person's body and mind. The attacking object can be itself, another person, or an object. Attacks on others include physical and sexual attacks that can cause injury, disability, and death. Attacks on objects can cause economic losses. In addition to the specific behaviors that appear, impulsive and violent tendencies can be expressed as potential behaviors, such as threatening speech or gestures. WHO (2002) has a broader definition of violence: Threats to use or have deliberately used force or power against themselves, others, a specific group of people or a particular society, causing or highly likely to cause injury, death, Psychological injury, deformity or living conditions are deprived."

Forced behavior: a neurosis characterized by obsessive-compulsive and forced movements. It is characterized by the simultaneous existence of conscious self-forcing and conscious self-reforcement. The patient knows that the persistence of obsessive-compulsive symptoms is meaningless and unreasonable, but it cannot be restrained and repeated. The more it tries to resist, the more nervous and painful. The continuation of the course can be a ritual movement, although the mental pain is significantly relieved, but its social function has been seriously impaired.
