Can non primates get mental illnesses like hysteria or obsessive compulsive disorder?

Yes, just like the mimosa in plants, non-primates can get it.

It is true that both dogs and parrots can suffer from obsessive-compulsive disorder and depression. In Europe and the United States, there are specialized animal psychologists.

Yes. Especially with a high level of spirituality, such as domestic dogs.

This is possible with habitual obsessive-compulsive disorder.

Obsessive-compulsive disorder is a kind of mental illness, it is necessary to see a psychologist, especially if you drag on for a long time, it is better to see a doctor, but there are also those who get better, that is very rare, at present, the international psychological counseling in China and Europe is more professional, regular, you usually read more books, it is helpful to yourself.

The reason may be the appearance, but the key depends on the essence. The essential reason is generally that people's own thinking at that time is relatively negative, and their personalities are imperfect, such as being cautious, pursuing perfectionism, etc., and their attention is always on negative things, which is easy to have psychological problems. Once something goes wrong (the fuse), psychological problems arise.

Obsessive-compulsive disorder is a kind of neurosis with self-compulsion as a prominent symptom, the symptoms of obsessive-compulsive disorder are characterized by self-compulsion, that is, the symptoms belong to the patient's self rather than external forces, it appears repeatedly against the patient's will, and the patient cannot control it, the patient feels that it is unreasonable or meaningless, and tries to get rid of and resist the compulsive content, and the appearance of the symptom compulsively and the patient's inner confrontation with the symptom causes the patient's anxiety and distress. Traditional Chinese medicine does not have a name for obsessive-compulsive disorder, and its symptoms are similar to those of "palpitations" and "apprehensions" in traditional Chinese medicine. The process of OCD is a process of psychological adjustment that goes hand in hand with medications.

It seems that there is no accurate explanation of the cause of obsessive-compulsive disorder.

In addition to depression and obsessive-compulsive disorder, mental illness also includes anxiety disorders and autism.

Neurosis is a very large concept, including panic disorder, generalized anxiety, social phobia, obsessive-compulsive disorder, etc., in different diagnostic systems, hysteria is included in neurosis, and some are placed alongside neurosis. In conclusion, hysteria is a mental illness, while neurosis is an umbrella term for several mental illnesses.

Then you can go! No one in this world can force you, what you want is your own freedom! I don't bother to say anything.
