Attention disorder

Introduction Note that a person's mental activity selectively points to a certain goal. There are active and passive points. Attention barriers manifest themselves in changes in intensity, range, and persistence. Individuals feel threatened. If they are suspected of being seriously ill or think that others are going to persecute him, they often show increased vigilance and attention. Sleepiness, fatigue, depression, and often distraction are difficult to concentrate. Children with ADHD (MBD) due to dysfunction of the brain up-regulation system, insufficient cortical arousal, weakened control of the cortical descending motion center, resulting in short-term attention and constant movement, although intelligence is collected in the normal medical teaching Poor academic performance. The basic psychological barrier is the attention deficit.

Cause

Attention disorders are often accompanied by disturbances of consciousness. Any part of the brain lesions, especially a wide range of lesions, cause damage to attention, a decrease in arousal, a high level of lethargy or awakening, and a state of nervous anxiety, which affects attention. Continuous concentration, schizophrenia and mild dysfunction syndrome in children also have attention deficits.

Attention to obstacles is very common. For example, parents often complain that the childs attention is not concentrated. There are many small movements in class. He knows it himself, but the child cant correct it himself. This is one of the obstacles.

There are six types of attention barriers, namely:

1. Attention to enhance: There are two kinds of attention enhancement. One is to pay attention to something that is external. For example, a patient with a delusional concept often pays attention to a systematic reverie to pay attention to the actions of the person he suspects. Even some tiny details remain highly noticed and alert. The other is to point to some physiological activities of the patient itself, such as the suspected concept of neurotic patients. These patients often pay too much attention to their own health status or the morbid thinking content that makes him sad, and it is difficult for any other event to transfer them. attention. Increased attention can enhance or promote the development of mental symptoms.

2. Attention to weaken: the performance is that the active attention is obviously weakened, that is, the attention is not concentrated, the patient can not concentrate on a certain thing and keep it for a long time, so that the attention is easy to disperse, even if the book is read for a long time, the result Still not knowing what it is, just like I haven't read it. More common in neurasthenia and schizophrenia.

3. Transferring with the environment: Excitability is manifested as passive attention, but attention is not persistent, and the object of attention is constantly shifting. If the mania is in an excited state, the attention is easily attracted by the new phenomenon of the field in the surrounding environment, so that the topic and the content of the activity are constantly changing, and the attention cannot be sustained, and the accidental changes will be The patient's attention is drawn to the other side. In the case of acute mania, the inconsistency of the patient's speech is mainly due to the constant conversion of the object of attention and the too fast thinking association.

4. Attention to dullness: the patient's attention is difficult to concentrate and slow, but the attention to stability is less, the patient is completely correct to answer the first question, but he continues to ask the second and third questions. At the time, the response of others seems slow, mainly due to the slow excitement of attention and the slow process of association, which is more common in depression.

5. Attention to stenosis: the patient's attention range is significantly reduced, active attention is weakened, when the patient concentrates on a certain thing, and other things that are generally easy to evoke attention do not cause the patient's attention, see the state of paralysis and dementia.

6. Attention to fixation: the patient's attention to stability is particularly enhanced. Seen in healthy people and mental patients, such as some inventors and thinkers, fixed attention to certain concepts, strong concepts control their entire consciousness, especially this thinking and equivalent When there is a strong emotional response, depression, and patients with stubborn delusions, will always be fixed on these delusions. In patients with obsessive-compulsive attitudes, patients with this state of mind are aware that such attention is concentrated and fixed and cannot be transferred, so it is also called mandatory attention.

Among them, attention to weakening and attention to stenosis is the most common. Attention disorders are often accompanied by disturbances of consciousness. Any part of the brain lesions, especially a wide range of lesions, cause damage to attention, a decrease in arousal, a high level of lethargy or awakening, and a state of nervous anxiety, which affects attention. Continuous concentration, schizophrenia and mild dysfunction syndrome in children also have attention deficits.

Differential diagnosis

Differential diagnosis of attention disorders:

From the appearance of dementia to death lasted about 4.2 months. At this time, the patient's blood was positive for HIV, and the cerebrospinal fluid was examined for inflammatory changes. Eeg shows extensive warm wave, ct shows atrophy of the cerebral cortex and enlargement of the ventricles.
