Prevalence and motor-functional correlates of frontotemporal-spectrum disorders in a large cohort of non-demented ALS patients.

Background: This study aimed at (1) delivering generalizable estimates of the prevalence of frontotemporal-spectrum disorders (FTSDs) in non-demented ALS patients and (2) exploring their motor-functional correlates.

Methods: N = 808 ALS patients without FTD were assessed for motor-functional outcomes-i.e.

Emotional awareness in patients with amyotrophic lateral sclerosis.

Introduction: It has been recently acknowledged that deficits in experiencing and processing one's own emotions, also termed alexithymia, may possibly feature the frontotemporal-spectrum disorders. This study aims to determine whether alexithymia could be included within the frontotemporal syndromes of amyotrophic lateral sclerosis (ALS).

Methods: Alexithymic traits were estimated in a cohort of 68 non-demented ALS patients with the 20-item Toronto Alexithymia Scale (TAS-20).

Loneliness as neurobehavioral issue in amyotrophic lateral sclerosis.

Objective: In elderly people loneliness represents a risk factor for dementia and may negatively impact on mental and physical health. The specific contribute of loneliness to cognitive and behavioral functioning have not yet been determined in amyotrophic lateral sclerosis (ALS). Our hypothesis was that loneliness may be related to motor dysfunction with a negative impact on cognitive and behavioral decline, possibly related to specific cortical involvement.
