Apathy and the Functional Anatomy of the Prefrontal Cortex–Basal Ganglia Circuits

Abstract

The clinical signs grouped under the concept of apathy are a common feature of prefrontal and basal ganglia lesions or dysfunctions and can therefore help to improve our understanding of the functional anatomy of the prefrontal-basal ganglia system. Apathy is here defined as a quantitative reduction of voluntary, goal-directed behaviors. The underlying mechanisms responsible for apathy can be divided into three subtypes of disrupted processing: 'emotional-affective', 'cognitive' and 'auto-activation'. Apathy due to the disruption of 'emotional-affective' processing refers to the inability to establish the necessary linkage between emotional-affective signals and the ongoing or forthcoming behavior. It may be related to lesions of the orbital-medial prefrontal cortex or to the related subregions (limbic territory) within the basal ganglia (e.g. ventral striatum, ventral pallidum). Apathy due to the disruption of 'cognitive' processing refers to difficulties in elaborating the plan of actions necessary for the ongoing or forthcoming behavior. It may be related to lesions of the dorsolateral prefrontal cortex and the related subregions (associative territory) within the basal ganglia (e.g. dorsal caudate nucleus). The disruption of 'auto-activation' processing refers to the inability to self-activate thoughts or self-initiate actions contrasting with a relatively spared ability to generate externally driven behavior. It is responsible for the most severe form of apathy and in most cases the lesions affect bilaterally the associative and limbic territories of the internal portion of the globus pallidus. It characterizes the syndrome of 'auto-activation deficit' (also known as 'psychic akinesia' or 'athymormia'). This syndrome implies that direct lesions of the basal ganglia output result in a loss of amplification of the relevant signal, consequently leading to a diminished extraction of this signal within the frontal cortex. Likewise, apathy occurring in Parkinson's disease could be interpreted as secondary to the loss of spatial and temporal focalization of the signals transferred to the frontal cortex. In both situations (direct basal ganglia lesions and nigro-striatal dopaminergic loss), the capacity of the frontal cortex to select, initiate, maintain and shift programs of actions is impaired.

  • Previous studies have implicated the role of the dorsomedial striatum, a known site of impairment in PD, in mediating goal-directed behaviors, such as the online monitoring and adjustment of vocal intensity in the LSVT LOUD program.

    “Previous studies have implicated the role of the dorsomedial striatum, a known site of impairment in PD, in mediating goal-directed behaviors (Haruno & Kawato, 2006; Levy & Dubois, 2006), such as the online monitoring and adjustment of vocal intensity in the LSVT LOUD program.”

    In “Role of Dopamine” (page not provided), the paper links dorsal-striatal signaling to action selection and discusses striatal dopamine depletion in PD. It also proposes a role for the dorsolateral PFC–dorsal caudate circuit in PD-related cognitive dysfunction. It does not specifically identify the dorsomedial striatum as the impaired site or examine online adjustment of vocal intensity in LSVT LOUD; the latter appears after the citation as the citing authors’ example.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
