Motor-Volitional Disorders

Motor-volitional disorders represent a group of psychopathologic states characterized by a severe distortion of a person's goal-directed activity, motivation, and emotional responsiveness. The key manifestations of this group include the apathy-abulia syndrome and various forms of acute affective reactions.

Main causeEnd-stage schizophrenia and organic lesions of the frontal lobes of the brain.
Pathological affectA brief psychosis with clouding of consciousness and subsequent complete amnesia.
ResponsibilityPhysiological affect occurs with a clear consciousness and does not exempt from criminal liability.
Sleep in depressionTotal sleep duration decreases; early morning awakenings are characteristic.

Apathy-abulia syndrome

This is a negative deficit disorder that is most often irreversible. It manifests as a profound impoverishment of will and emotions. Patients demonstrate total apathy and indifference to their surroundings. They become inconspicuous, preferring to spend all their time in bed or sitting alone, and may spend hours staring mindlessly at the television without retaining information.

Severe moral and ethical degradation develops: patients experience no sense of shame, duty, or responsibility, and cannot be engaged in labor. A complete loss of basic hygiene skills is characteristic. Patients stop washing, brushing their teeth, refuse haircuts, and go to bed in outer clothing purely out of laziness. The reduction of volitional control leads to the disinhibition of primitive instincts. Hypersexuality and gluttony appear; patients may make obscene hints to relatives or urinate directly in bed because they are too lazy to walk to the restroom. Patients completely lack insight into their condition, feel no suffering, and voice no complaints.

Pathological and physiological affects

Affects are reactions to acute emotional trauma, yet they differ cardinally in mechanism and manifestations.

  • Pathological affect is a brief acute psychosis occurring with twilight clouding of consciousness. It shares general pathogenetic features with epilepsy: stress merely triggers latent convulsive brain activity (often against the background of previous head trauma). The attack lasts a matter of minutes and is accompanied by frenzy, colossal cruelty, and complete detachment of the patient. The state ends in severe exhaustion and terminal sleep. Absolute amnesia ensues upon waking — the person does not remember their actions and is genuinely surprised by what happened.
  • Physiological affect proceeds differently. Consciousness remains clear, and the person understands the danger of their actions. This is a violent reaction to stress (jealousy, fights), often found in explosive-type psychopathic personalities.

Forensic psychiatric significance

Differential diagnosis of affective disorders is critically important in forensic psychiatry. The main diagnostic criterion differentiating the two types of affects is the state of consciousness at the moment of the act.

In pathological affect, clouding of consciousness is recorded, which serves as an absolute basis for declaring a person insane (non-compos mentis). They are not subject to criminal liability because they could not control their actions. Conversely, physiological affect occurs with clear consciousness, so the subject is recognized as sane (compos mentis) and bears full criminal liability for committed crimes.

Other affective and volitional disorders

In addition to deficit syndromes, productive affective disorders are distinguished. Depression usually lasts several months and in most cases arises without an apparent external cause. It is accompanied by decreased sleep duration, early awakenings, and anhedonia. Severe forms with high suicidal risk are characterized by a painful sensation of tightness behind the sternum. There is also larvated depression, which masks itself as somatic disorders.

Mania, by contrast, manifests as a reduced need for sleep, a placid mood, and a pathological urge to help everyone around. Specific mood changes include dysphoria (most typical of epilepsy) and euphoria (often accompanying intoxications). Among drive disorders are obsessive disorders, in which patients are able to control their behavior according to the situation, and pathologies such as dromomania (impulse to wander).

Briefly: answers to topical questions

What are the stages of the course of pathological affect?

The course of pathological affect comprises the period of psychosis itself, the outcome, and the post-psychotic period.

  • At the moment of psychosis — clouding of consciousness accompanied by frenzy, striking cruelty of the committed violence, and detachment (bystanders cannot correct the patient's actions).
  • Duration and outcome — lasts a few minutes, concluding with severe exhaustion (patients drop from exhaustion, often falling into a deep terminal sleep).
  • Post-psychotic period — complete amnesia for everything that happened, extreme astonishment and disbelief regarding the actions committed.

What types of impulse control disorders exist?

Impulse control disorders include various urges toward antisocial acts. The following types are distinguished:

  • Theft (kleptomania) — the urge to commit thefts.
  • Wandering (dromomania) — the urge to wander.
  • Arson (pyromania) — the urge to commit arson.
  • Gambling (gambling disorder / ludomania) — the urge to gamble.

Also included among impulse drives is dipsomania.

What is the classical triad of symptoms characteristic of manic syndrome?

The classical symptom triad of manic syndrome includes three main manifestations.

  • Elevated mood (hypertimia) — very good mood, inflated self-esteem, optimism, and hedonism.
  • Accelerated thinking (tachypsychia) — acceleration of thought processes.
  • Psychomotor agitation — pronounced motor activity that is always goal-directed (drive toward actions and activity), but due to high distractibility, patients do not follow tasks through to completion.

What symptoms are included in the classical depressive triad?

The classical depressive triad includes three main symptoms that are the direct opposite of the manic triad.

  • Lowered mood (hypotimia) — the main syndrome-forming sign, manifested by complaints of anguish, despondency, anxiety, and sadness unrelated to the real situation.
  • Thought slowing (associative inhibition) — impoverished, monosyllabic speech, prolonged deliberation over answers, and difficulty comprehending questions.
  • Motor retardation (psychomotor retardation) — stiffness, sluggishness, clumsiness, which in extreme cases can progress to depressive stupor (complete immobility).

What is catatonic stupor and what are its types?

Catatonic stupor is a state of complete or partial immobility expressed by general rigidity, amimia, and a lack of vivid reactions to the environment. According to the state of consciousness, the following types of catatonia are distinguished:

  • Lucid catatonia (lucidus) — develops against the background of clear consciousness, is characteristic of malignant variants of schizophrenia, and has an unfavorable prognosis.
  • Oneiric catatonia — catatonic symptomatology combined with dreamlike (oneiric) clouding of consciousness; it represents an acute psychosis with a favorable prognosis.

Which volitional disorders belong to hyperbulia?

Hyperbulia represents a general enhancement of all basic drives. The clinical manifestations of this disorder include:

  • Increased appetite — an increased need for food.
  • Increased sexual drive — in women, manifested by the urge to dress up and coquetries; in men, by heightened attention to appearance, courting, and compliments.
  • Increased need for socialization — intrusiveness, talkativeness, constant interference in strangers' conversations, giving advice, and striking up conversations with strangers on the street.
  • Increased need to nurture — the urge to provide help and care to others.
How to memorize

To memorize the difference between affects: C — Clear (Clear consciousness, responsibility exists). P — Pathological (Psychosis/clouding, Permanent amnesia, Patient is not sane / irresponsible).

Class and exam questions

Do patients with apathetic-abulic defect realize their illness?

No, insight into the condition is completely absent. Patients do not consider themselves ill, do not suffer because of their defect, and do not present complaints.

Does the patient remember their actions during a pathological affect?

No, this condition is characterized by complete post-psychotic amnesia due to twilight clouding of consciousness. Patients do not believe bystanders' accounts of the violence committed.

What is the main difference between a pathological affect and a physiological affect?

The key diagnostic criterion is the state of consciousness. In pathological affect, clouding of consciousness is observed, whereas in physiological affect, consciousness remains clear.
