Typically, finger agnosia does not present difficulties in daily life.

There is a strong link between acalculia and finger agnosia.

There is no known treatment for finger agnosia.

Any damage to that blood supply would cause symptoms of both acalculia and finger agnosia.

They concluded that the areas underlying finger agnosia and acalculia are extremely close to one another, but distinct.

Patients with finger agnosia may have difficulty selectively moving fingers, regardless if it is by command or imitation.

Although it is a necessary component of Gerstmann's syndrome, cases of finger agnosia alone have been reported.

Usually, lesions to the left angular gyrus and posterior parietal areas can lead to finger agnosia.

In a study by Rusconi et al., repetitive transcranial magnetic stimulation was used in healthy individuals to simulate finger agnosia.

Acalculia is one out of four defining components of Gerstmann's syndrome; the other three components are agraphia, finger agnosia, and right/left confusion.

Finger agnosia: An inability to name the fingers, move a specific finger upon being asked, and/or recognize which finger has been touched when an examiner touches one.

Della Sala et al. reported a woman with a stroke in the left subcortical posterior parietal area who had only finger agnosia a year and a half later.

It is one of a tetrad of symptoms in Gerstmann syndrome, although it is also possible for finger agnosia to exist on its own without any other disorders.

Persons with finger agnosia are able to name and point to a finger when able to use visual guidance, but will have more errors than a person without the disorder.

Gerstmann studied patients whose deficits were in the body schema and thus lacked the ability to recognize, identify or name the fingers on either hand, a phenomenon known as finger agnosia.

In their 2005 study with repetitive transcranial magnetic stimulation (rTMS), they noted both finger agnosia and acalculia in the test subjects when areas of the intraparietal sulcus were stimulated.

The case study reports that the patient also demonstrated "severe finger agnosia, and in fact the finger agnosia appeared to be directly related to her inability to perform calculations."

Lesions to the left angular gyrus are associated with finger agnosia, as well as the other symptoms of Gerstmann Syndrome, also known as Angular Gyrus Syndrome.

Acalculia is sometimes observed as a "pure" deficit, but is commonly observed as one of a constellation of symptoms, including agraphia, finger agnosia and right-left confusion, after damage to the left angular gyrus, known as Gerstmann's syndrome.

Finger agnosia, first defined in 1924 by Josef Gerstmann, is the loss in the ability "to distinguish, name, or recognize the fingers", not only with the patient's own fingers, but also the fingers of others, and drawing and other representations of fingers.
