Numbness in the fingers of my left hand

Numbness of the fingers of the left hand has recently become quite common. It can be accidental due to short-term compression of the nerve, or pathological, manifesting itself as a sign of another, more serious disease.

Dangling hand: causes, symptoms, diagnosis

In neurological practice, sometimes we encounter patients with wrist-drop syndrome, in whom tendon reflexes on the hands are evoked (they are not reduced), and their possible increase seems doubtful. The absence of conclusive sensory disturbances makes it difficult to interpret such a clinical picture. Wrist-drop is a symptom similar to foot-drop.

Muscle atrophy (amyotrophy) of the hand: causes, symptoms, diagnosis

In the practice of a neurologist, muscle atrophy (amyotrophy) of the hand is encountered in the form of secondary (more often) denervation atrophy (due to a disruption of its innervation) and primary (less often) atrophy, in which the function of the motor neuron is generally not affected (“myopathy”).

dystonia

Primary and secondary forms of dystonia are distinguished, and their clinical manifestations depend on the etiology. Dystonia is a syndrome manifested by deforming movements and postures that arise as a result of simultaneous involuntary contraction of agonist and antagonist muscles.

Chorea

Chorea - irregular, abrupt, disordered, chaotic, sometimes sweeping, aimless movements, occurring mainly in the limbs. Mild choreic hyperkinesis may manifest itself as mild motor restlessness with excessive fussy movements, motor disinhibition, exaggerated expression, grimaces and inadequate gestures.

Tremor: causes, symptoms, diagnosis, treatment

Tremor is an involuntary oscillation of any part of the body caused by alternating or synchronous contractions of reciprocally innervated muscles. Diagnosis of the underlying disease is often a very complex task, the solution of which requires, first of all, a correct syndromic description of the tremor. What causes tremor? Types of tremor. Rest tremor. Postural tremor. Intention tremor. Rubral tremor. Psychogenic tremor. Physiological tremor. Essential tremor. Cerebellar tremor. Tremor treatment

Myoclonus

Myoclonus is a sudden, brief, jerky muscle twitching that occurs as a result of active muscle contraction (positive myoclonus) or (rarely) a drop in postural muscle tone (negative myoclonus).

Nervous tic

Tics are typically short, relatively elementary, stereotypical, normally coordinated but inappropriately performed movements that can be suppressed by willpower for a short period of time, which is achieved at the cost of increasing emotional tension and discomfort.
