So, both apathy Exotic Tropical Fruits fatigue manifest in difficulty in starting llack maintaining the usual or desired activities, and ,otivation suggests that for both there is a perturbation in effort-based decision-making, which results in lower willingness to engage in effortful od 1112 motivatioj, In addition, apathy and fatigue may often be confused due to their similar manifestations and repercussions.

They are nevertheless two xnd conditions that Exotic Tropical Fruits occur alone or motivahion concomitant 14 Despite their negative impact on healthy motivatlon and their clinical relevance in pathological populations, the exact relationships between apathy and fatigue are still motifation understood, and differentiating them is mofivation difficult.

Apathy and motivqtion are both multidimensional concepts, and their various Fatjgue might be differently related to each other and overlap to some extent. Mtoivation far, two studies have already lacm correlational analyses between apathy and laack subscales 3 Interestingly, they motivxtion significant links between all apathy and fatigue subscores, with if correlations between fatigue Optimal blood pressure range behavioral apathy, Fatjgue mainly negative correlations between fatigue and emotional apathy.

Lafk aim of the present laxk was twofold: to describe mitivation associations laci the subdimensions of apathy and fatigue through correlation analyses, and to Quick and easy diabetic meals their motovation and dissociations through exploratory lac, analyses EFA in motivxtion representative laxk of healthy participants.

The EFA allows to explore the structure of the relationships between variables and allows to identify latent factors. The Apathy Motivation Index AMI and Dimensional Apathy Scale DAS were used to assess apathy 3 The Multidimensional Fatigue Inventory MFI was used to assess fatigue We hypothesized that the co-occurrence of apathy and fatigue would be underpinned by common latent factors, although they would also be distinguishable on other dimensions, confirming the importance of differentiating them in the general population.

Results may have also important clinical implication for pathological population such as in neurocognitive disorders and Parkinson disease, where apathy and fatigue are highly prevalent.

Total AMI scores ranged from 0. Total DAS scores ranged from 9 to 50 with a mean of Total MFI scores ranged from 20 to with a mean of The range, the average, the standard deviation of subscales, the skewness of data see Supplementary Table S1 and frequency histograms are provided in supplementary materials see Supplementary Fig.

For the AMI, the behavioral and social subscores were positively correlated with all subscores of MFI, whereas the emotional subscale was negatively correlated with the MFI subscales.

For the DAS, the initiation and executive subscores showed positive correlations with all subscores of MFI. Association between fatigue and apathy: correlations between total MFI score and a total AMI score and b total DAS score. The sampling adequacy was good, with a KMO value Kaiser—Meyer—Olkin of 0.

Thus, we were able to perform an EFA on all items. A five-factor structure was found to be the most relevant in light of the scree plot, which showed a plateau in eigenvalues after five factors see Supplementary Fig.

Results are presented in Table 2 and Fig. Schematic five-factor structure. The five gray boxes correspond to the five latent factors. Items inside a gray box means that they are supported by the corresponding factor. Blue boxes contain MFI items. Orange boxes with full lines contain items from apathy questionnaires belonging to the same subdimension e.

Orange boxes with dashed lines include DAS and AMI items belonging to the same apathy subdomain. We can see overlapping between apathy and fatigue when the blue and orange boxes touch each other. Factor 1 mostly comprised the items from the DAS executive subscale and the items of the mental fatigue subscale of the MFI, indicating that the executive dimension of apathy and the mental dimension of fatigue share the same latent factor.

Factor 2 included only MFI items, mainly those assessing general and physical fatigue. Factor 3 included initiation and behavioral subscales from the DAS and AMI, as well as some items of reduced activity and reduced motivation from the MFI, indicating overlap.

Factor 4 comprised only emotional subscales from the AMI and DAS. Factor 5 mostly comprised social items from the AMI and some items of initiation from the DAS. A lack of energy and a lack of motivation are frequently reported in the healthy population. These conditions can persist over time and have repercussions on daily functioning.

Apathy and fatigue may appear to be similar, suggesting an overlap, and this has prompted questions about the characteristics that distinguish them. The aims of this study were to describe the relationship between apathy and fatigue by examining the multidimensions of these two concepts, and to investigate their overlaps and dissociations in a big sample of healthy participants.

As expected, converging with previous studies 311we found several correlations between the subdimensions of apathy and fatigue. The exploratory factor analysis EFA revealed overlaps in the reduced activity and mental domains, while the emotional and social domains were found to differ, thus distinguishing apathy from fatigue.

The executive dimension of apathy, representing reduced motivation for organization, attention and planning, showed the strongest correlations with the fatigue scores.

The strongest association was found with mental fatigue, representing a feeling of mental lassitude, and both appeared to be underpinned by the same latent factor, according to the EFA.

Items from the fatigue questionnaire about reduced activity and reduced motivation were widespread across the factors that support apathy and fatigue factor 1: executive apathy and mental fatigue, factor 2: general and physical fatigue, factor 3: behavioral apathy.

This is consistent with prior knowledge that both apathy and fatigue manifest as reduced activity 1171819 In addition, the overlap of the fatigue items of reduced motivation with the factor that expresses behavioral apathy is also consistent as, conceptually, apathy is defined as a lack of motivation.

Unsurprisingly, the items of initiation and behavioral activation from the AMI and DAS were associated. Further, their latent factor comprised items of reduced activity from the MFI, indicating an overlap. Similarly, the emotional items of the two scales were associated.

However, the factor that underpinned emotional apathy did not support any items of fatigue, similar to the last factor of social behavior apathy, indicating that emotional and social components are proper to apathy and do not show specific overlaps with fatigue.

This confirms the importance of assessing emotional and social apathy components separately from behavioral components which mainly manifest through behavioral symptoms, and are more closely associated with fatigue 1 Our findings are consistent with results of Ang et al.

which reported significant positive correlations between fatigue and behavioral activation as well as social motivation, and negative correlations between fatigue and emotional subdimension of AMI 3.

Our results converge also with those of Jurgelis et al. Indeed, we also found correlations between fatigue and executive and action initiation subdimension of DAS. However, in our study we did not found correlations between the emotional subdimension of DAS and MFI scores.

Going beyong correlation, in the present study, we employed an EFA to investigate overlaps and differences between apathy and fatigue components. Results showed that apathy and fatigue have reduced activity and mental difficulties in common, whereas emotional and social disorders distinguish apathy from fatigue.

More specifically, significative differences in fatigue were found between apathetic versus non-apathetic patients for the reduced activity, reduced motivation and mental fatigue items 21and when apathy was evaluated in fatigued and non-fatigued patients, action initiation and intellectual curiosity but not emotion were found to be significantly different These similarities between results found in healthy participants and different types of patients suggest that similar mechanisms could underlie apathy and motivation in healthy people and pathological populations.

This is an interesting area for future investigation. The similarities between apathy and fatigue may be explained by a shared neurobiological basis.

Fatigue is a multifactorial phenomenon and knowledge about its etiology is still limited, but it has been proposed that fatigue may be the consequence of a disturbance in frontal-basal ganglion axis 24 Several studies found that fatigue is associated to high perception of effort and, similarly to apathy, the neurocognitive framework of effort-reward decision making has been proposed to explain at least partially this symptom 12 The anterior cingulate cortex and the ventromedial prefrontal cortex play a role for compute the value of effort and the subsequent effort-based decision making Studies in fatigue highlighted also the role of sensorimotor and interoceptive information on the effort value which is notably underpinned by the premotor cortex and the insula 7 It has been proposed that these brain regions form together with the dorsolateral prefrontal cortex a circuit in charge of effort-reward decision making, and that the high weighting of effort cost in fatigue may explain the lower engagement in activities.

So, disturbances in the prefrontal-basal ganglia loop have been identified for both apathy and fatigue 28 However, evidence suggests that disruption in this brain regions are differently related to the dimensions of apathy. Kumfor et al. Other neuroimaging studies also found evidence that behavioral, cognitive and emotional dimension of apathy may have distinct neuroanatomical bases Behavioral and psychological symptoms such as fatigue, apathy, depression and anhedonia can result in similar observable disorders, making differential diagnosis not trivial.

Our findings have important implications for the general population, and may has also implication for neurocognitive and psychiatric disorders.

It can help in clinical practice to disentangle symptoms.

What to know about lethargy	Acute diarrhea is the most common form, with bout usually lasting days. Chronic diarrhea can last for 4 or more weeks and is often a sign of a more serious underlying illness. What is Nausea and Vomiting? Vomiting is the uncontrollable need to evacuate the contents of the stomach through the mouth. Vomiting is commonly known as throwing up, being sick or spewing. The physical health impacts of the novel Coronavirus COVID pandemic are well known, as is the economic impact.

Fatigue - More Than Just Feeling Tired What is Fatigue? Fatigue is a general feeling of exhaustion - a lack of energy and motivation that persists no matter how well rested you are. While some people suffering fatigue may feel drowsy, sleepiness is not synonymous with fatigue. Diagnosis of Fatigue A constant lack of energy, often combined with a lack of motivation and easily becoming exhausted are hallmarks of fatigue. Common Fatigue Symptoms When suffering fatigue, a person will have a constant lack of energy no matter how much sleep they have had. Causes of Fatigue There are many potential causes of fatigue typically broken into three categories. These factors include: Alcohol - excessive or prolonged alcohol consumption Boredom Caffeine - excessive caffeine consumption can cause fatigue Diet - eating a diet with insufficient nutrients Drug use - many illicit drugs, especially stimulants. Prescribed drugs, including sedatives and antidepressants can also cause fatigue. Emotional turmoil - periods of extreme emotion such as grief can lead to fatigue Physical exertion - both excessive and insufficient physical exercise can lead to fatigue Sleep - a lack of sleep or too much sleep can lead to the same end Weight - being overweight or obese 3. Some common mental health issues leading to fatigue include: Anxiety Depression Seasonal Affective Disorder Stress Fatigue Self Care As there are so many potential causes of fatigue there is no definitive self care methodology available. You should immediately see a doctor if fatigue is felt in conjunction with one of the following: Bleeding - vomiting or passing blood Chest pain Headache - severe debilitating headaches Faintness or confusion Irregular heartbeat Shortness of breath Severe abdominal, back, neck or pelvic region Thoughts of suicide, self hard or violence towards others To talk to a doctor about your feelings of fatigue and to get medical advice, the easiest and most convenient way to book online is through MyHealth1st.

Coronavirus Symptoms One of the difficulties of diagnosing COVID outside of official coronavirus testing is the fact that the virus shares most common symptoms with the common cold. Diarrhea: Causes, Prevention and Treatment Diarrhea is typified by increased frequency of bowel movement and loose, watery stools. Mental Health in the Time of COVID The physical health impacts of the novel Coronavirus COVID pandemic are well known, as is the economic impact. First, this study is based uniquely on self-report questionnaires, which carry the risk of subjectivity. Future study should complement self-assessment with behavioral tasks such as effort-based tasks and more objective apathy proxies e. Second, it would be important to assess whether factors potentially affecting apathy and fatigue such as depressive symptoms, anxiety, substance use, or the presence of chronic illness modulate the observed relationship, by adding specific questionnaires assessing those symptoms and pathologies. So, results should be taken with caution because they could not be representative of the general population in its natural state before the pandemic. It would be important to replicate the findings in the future in an independent sample of participants. We presented information about the study, requested consent to participate, and then asked them to complete anonymous, self-report questionnaires online on the Qualtrics platform. Inclusion criteria was to be over 18 years old. The study was performed in accordance with the Declaration of Helsinki, and approved by the Ethical committee "Comité de Protection des Personnes—CPP Est III, France, MoTap: RCB ID No. Subjects provided informed written consent for their participation. The data collection was performed between December and March Participants were asked to complete three validated questionnaires that assess apathy and fatigue as multidimensional constructs. The Apathy Motivation Index AMI 3 is a self-administered item scale to assess motivation and apathy in healthy people. Each item is negatively scored from 0 completely true to 4 completely untrue such that a higher score indicates greater apathy. The AMI is composed of six items for each of three subscales: behavioral activation goal-directed behavior initiation, e. We employed the French version of the AMI f-AMI validated by Corveleyn and colleagues submitted. The AMI score were calculated by taking the mean rating of the items within subscales. The Dimensional Apathy Scale DAS 16 is a self-administered item scale to assess the lack of motivation for planning, organization and attention executive, e. A higher total score indicates more lack of motivation. The Multidimensional Fatigue Inventory MFI 17 is a item self-report questionnaire for measuring five dimensions of fatigue: general fatigue e. Each subscale contains four items, which are scored on a five-point Likert-scale. Scores range from 4 absence of fatigue to 20 maximum fatigue for each subscale. We employed the French version validated by Gentile et al. Statistical analyses were performed using R Studio software. Here, results of Spearman analysis are presented, as data are not normally distributed. We verified whether removing outliers changed the pattern of results. As no difference in the pattern of results was found removing the outliers, we decided to keep all participants in the analyses. Considering the high number of correlations analysis, we applied an alpha level at 0. An exploratory factor analysis EFA was used to explore the structure of the relationships between variables and allowed to identify latent factors. The KMO tested the sampling adequacy. It informed us about the proportion of common variance and variance that can be explained by other variables. A KMO value better than 0. To determine the number of factors, the eigenvalue table and the scree plot were examined. Factors included items with a loading of at least 0. Miller, D. et al.
