näköpseudohallusinations

Visual pseudo-hallucinations are perceptions of visual stimuli that are not actually present in the external environment, but are experienced in a way that is distinct from a true hallucination. Unlike true hallucinations, which are fully formed and convincing, pseudo-hallucinations are often described as being superimposed on the visual field or appearing as if seen through a window. They can be simple, such as flashes of light or geometric shapes, or more complex, like distorted images or brief figures.

The distinction between visual hallucinations and pseudo-hallucinations lies in the subjective experience of the individual. While both involve seeing something that isn't there, pseudo-hallucinations are typically recognized by the person experiencing them as unreal or as an internal phenomenon. They may also be perceived as less vivid or less immersive than true hallucinations.

These phenomena can arise from a variety of causes. They are commonly associated with neurological conditions such as migraines (especially visual aura), epilepsy, and certain types of brain injury. Ophthalmological conditions, including macular degeneration or optic neuritis, can also lead to visual disturbances that might be perceived as pseudo-hallucinations. Furthermore, psychological factors, stress, and fatigue can sometimes contribute to their occurrence. Treatment depends on the underlying cause, and may involve managing the primary condition or addressing specific symptoms.
