The aetiological factors of BD include genetic factors, given great relevance due to its heritability (as high as 78%<a class="elsevierStyleCrossRef" href="#bib0020">4</a>), and environmental factors, which interact with the genetic factors to produce the disorder.<a class="elsevierStyleCrossRef" href="#bib0025">5</a> In addition to these factors, recent studies have shown abnormalities in structural connectivity detected by diffusion tensor imaging (DTI), a magnetic resonance imaging technique which provides a better definition of white matter.<a class="elsevierStyleCrossRef" href="#bib0030">6</a>DTI studies have provided extensive information about the structure of the white matter of patients with BD. However, these findings have to be interpreted with caution because of certain factors which may influence the results, such as the effects of medication, the different clinical phases of the disorder and age. The ideal could be to assess the connectivity in an asymptomatic population without medications. Still, as that is not always possible, one option would be to study it in the relatives of patients at high risk of acquiring BD, given its high heritability.<a class="elsevierStyleCrossRef" href="#bib0035">7</a> As the onset of symptoms is during adolescence or early adulthood, the ideal population would be children or adolescents. Therefore, this article aims to review the literature on changes in white matter integrity determined by DTI in child and adolescent relatives of patients with BD.MethodsSearch strategyWe searched through PubMed for studies with DTI which included children or adolescents related to individuals with BD. No date limitation was placed on the articles found and only articles published in English were included. We searched for the following keywords: “bipolar disorder, diffusion tensor imaging, white matter, first-degree relatives, offspring”.DTI, basic conceptsMRI works by measuring the proton signals from the water molecules making up much of the human body. In the brain, these molecules circulate in a space restricted by axons and membranes, leading to different diffusion patterns. The images of these patterns are what enable us to visualise the structure of brain tissue and its axonal organisation.<a class="elsevierStyleCrossRef" href="#bib0040">8</a>The need to obtain greater sensitivity in water diffusion signals, to enable better definition of structural connectivity, the group of connections between neuronal units, has led to the development of new magnetic resonance imaging techniques. One of these is DTI. This method uses different measurements<a class="elsevierStyleCrossRef" href="#bib0045">9</a>:<ul class="elsevierStyleList" id="lis0005"><li class="elsevierStyleListItem" id="lsti0005">•Fractional anisotropy (FA): determines the degree to which water diffusion is restricted to one direction with respect to other directions. It is scored from 0 to 1, with 0 being fully isotropic (homogeneous) diffusion of water in all directions and 1 being diffusion restricted to one direction only. In the brain, this property depends on the integrity of the axon tracts.</li><li class="elsevierStyleListItem" id="lsti0010">•Axial diffusivity (AD): reflects the rate of movement of water molecules parallel to the direction of the axons and is related to the diameter and organisation of the fibres.<a class="elsevierStyleCrossRef" href="#bib0050">10</a></li><li class="elsevierStyleListItem" id="lsti0015">•Radial diffusivity (RD): reflects the rate of movement of water molecules perpendicular to the direction of the axons.

With this field, the extent of diffusion of water molecules in different directions is measured. Employing tractography, the white matter tracts are plotted in three dimensions (according to the direction in which the water molecules move). These tracts can be located on three different axes, one from right to left (x), one anterior-posterior (y) and the other rostral-caudal (z). According to their location, the tracts are plotted in different colours: red for the x axis, green for the y axis and blue for the z axis<a class="elsevierStyleCrossRef" href="#bib0040">8</a> (<a class="elsevierStyleCrossRefs" href="#fig0005">Figs. 1 and 2</a>).<elsevierMultimedia ident="fig0005"></elsevierMultimedia><elsevierMultimedia ident="fig0010"></elsevierMultimedia>There are two main limitations to white matter visualisation by DTI: the measurement of the behaviour of the water molecules, which is an indirect measurement of neuroanatomy, and the low resolution of the images. In view of these limitations, the conclusion is that DTI resonance only provides a macroscopic view of the tracts and their anatomical limits are only poorly defined. Microscopic or histological techniques would be necessary for more precise definition. Despite these limitations, however, DTI has meant an advance in the definition of white matter and provides information which is difficult to obtain using histological techniques.<a class="elsevierStyleCrossRef" href="#bib0065">13</a>Normal development of white matter in childhood and adolescence and correlation with DTI findingsThe early stages of life involve major transformations in the human brain which contribute to neurodevelopment, but also represent a risk for the onset of some mental disorders.<a class="elsevierStyleCrossRef" href="#bib0070">14</a> The psychological, physical and social spheres undergo a series of changes during this period which seem to be mediated by neurobiological variations.<a class="elsevierStyleCrossRef" href="#bib0075">15</a>The different structural changes in the white matter are best characterised by DTI. This technique has made it possible to follow the development of white matter from birth to adulthood.<a class="elsevierStyleCrossRef" href="#bib0080">16</a>Childhood is a crucial stage for brain development, especially in the first two years of life. The brain increases in size by 101% in the first year and 15% in the second. The initial growth is mainly of grey matter, with only a minimal increase in the white matter in the first two years and much slower growth.<a class="elsevierStyleCrossRef" href="#bib0045">9</a>Changes in the development of white matter over the course of life have been inferred from DTI measurements, primarily from FA and MD. In general, an increase in FA has been found from childhood to adulthood, with a peak between the ages of 20 and 42, and then a slow, gradual decline.<a class="elsevierStyleCrossRef" href="#bib0050">10</a> MD tends to decrease until it reaches its lowest values between the ages of 18 and 41, and then increases in late adulthood; RD and AD measurements follow a similar pattern to DM.<a class="elsevierStyleCrossRef" href="#bib0050">10</a>The myelination process begins in the embryonic period and extends into adulthood. DTI studies have identified three stages in the development of white matter. In the first, an increase in RD and AD can be seen by the progressive organisation of the nerve fibres, as well as an increase in the AD of water, which reflects the increase in oligodendrocytes in the premyelination stage. In the second, there is a decrease in the diffusivity of water due to an increase in the density of the membrane caused by growth of the cytoskeleton and the proliferation of glial cells. Finally, the third stage shows an increase in FA which corresponds to the covering of axonal fibres by oligodendrocytes.<a class="elsevierStyleCrossRef" href="#bib0045">9</a> Studies with DTI have shown that this increase in FA is greater in the first 24–36 months of life, and is faster in the anterior than in the posterior structures, although the anterior structures are less developed in the neonatal stage.<a class="elsevierStyleCrossRef" href="#bib0085">17</a>Myelination occurs first in the most proximal and central pathways, the sensory pathways, the occipital pole and the projection fibres.<a class="elsevierStyleCrossRef" href="#bib0045">9</a> The cerebellar pons and cerebellar peduncles are the first brain structures to become myelinated, and this happens during pregnancy. At three months of age, the posterior limb of the internal capsule, the splenium of the corpus callosum and the optic radiation are myelinated. Subsequently, at the age of six months, myelination occurs in the genu of the corpus callosum and the anterior branch of the internal capsule.<a class="elsevierStyleCrossRef" href="#bib0045">9</a> The development in early stages of the corpus callosum, along with other structures such as the fornix and the inferior longitudinal fasciculus, seems to be explained by the basic functions they fulfil; the corpus callosum is involved in the interhemispheric connection processes, the fornix, in memory, and the inferior longitudinal fasciculus, in visual processing.The cingulum and the uncinate and superior longitudinal fasciculi, important tracts connecting the temporal and frontal regions, develop slowly during childhood and adolescence.<a class="elsevierStyleCrossRef" href="#bib0050">10</a> In the cingulum, FA values have been found only to reach their maximum peak after the age of 40, and then have slower reductions as a person gets older. A similar trend has been found in the uncinate and superior longitudinal fasciculi.<a class="elsevierStyleCrossRef" href="#bib0050">10</a> The corticospinal tract has been found to reach its maximum peak of increase in FA before the peak of the frontotemporal tracts and it resembles the pattern of the anterior limb of the internal capsule.<a class="elsevierStyleCrossRef" href="#bib0050">10</a>During adolescence, significant changes in DTI measurements have been found in the superior longitudinal fasciculus, corona radiata, thalamic fibres, inferior fronto-occipital fasciculus and internal capsule.<a class="elsevierStyleCrossRef" href="#bib0090">18</a> The increase in FA in these tracts may be mediated by a decrease in RD, which in turn reflects an increase in axon calibre and myelination.<a class="elsevierStyleCrossRef" href="#bib0095">19</a>The progressive increase in FA values during child and adolescent brain development seems to be correlated with the structural formation of microtubules, the organisation of neurofilaments, the increase in axon diameter, and dendritic arborisation. All these processes involve the maturation and organisation of the white matter and also therefore, the development of more complex cognitive and executive capacities.<a class="elsevierStyleCrossRef" href="#bib0085">17</a> A correlation has been found between working memory, visual processing, IQ and reading skills with increased FA in the different areas related to these functions.<a class="elsevierStyleCrossRef" href="#bib0095">19</a>DTI can provide important information on the microstructure and development of white matter. These findings need to be taken into account when interpreting the images of individuals who are in stages of growth and brain development.<a class="elsevierStyleCrossRef" href="#bib0045">9</a>Findings in the DTI of children and adolescents with BDOne meta-analysis<a class="elsevierStyleCrossRef" href="#bib0100">20</a> found an estimated prevalence of BD in children and adolescents of 1.8%, while in another study,<a class="elsevierStyleCrossRef" href="#bib0105">21</a> the estimated prevalence for the entire bipolar spectrum was 2.06%.

Most of them have been carried out with adults and differences have been shown in FA measurements comparing patients with BD and healthy individuals with no genetic predisposition (<a class="elsevierStyleCrossRef" href="#tbl0010">Table 2</a>). Emsell et al.<a class="elsevierStyleCrossRef" href="#bib0155">31</a> found a decrease in FA in the uncinate and superior longitudinal fasciculi of subjects with familial risk of BD, and Chaddok et al.,<a class="elsevierStyleCrossRef" href="#bib0160">32</a> although finding no significant differences in FA between at-risk relatives and controls, did find that these individuals had intermediate FA values, somewhere between patients with BD and controls, in the corpus callosum and the left and right superior longitudinal fasciculi.<elsevierMultimedia ident="tbl0010"></elsevierMultimedia>Some studies did find alterations. In the study by Mahapatra et al.,<a class="elsevierStyleCrossRef" href="#bib0165">33</a> lower FA values were found in the corpus callosum, the dorsal and hippocampal part of the right cingulum, and the uncinate fasciculus in relatives of patients with BD than in individuals without familial risk of the disorder. Another study<a class="elsevierStyleCrossRef" href="#bib0170">34</a> carried out on 15 healthy siblings of patients with BD found that they had white matter alterations in the right temporal region, which although significant compared to healthy controls, were not as large as in the group of patients with BD; in fact they lay in between. Linke et al.<a class="elsevierStyleCrossRef" href="#bib0175">35</a> found decreased FA in the right anterior limb of the internal capsule and in the right uncinate fasciculus in both patients with BD and first-degree relatives, while the corpus callosum was only affected in the patients with BD. This finding could indicate that alteration of the corpus callosum is a later marker in the course of the disease.Changes in structural connectivity in the relatives of patients with BD seem to be different depending on which type the patient has: BD I or BD II. Foley et al.<a class="elsevierStyleCrossRef" href="#bib0180">36</a> found no differences between relatives of patients with BD II and controls, while the relatives of patients with BD I showed a decrease in FA in the left uncinate fasciculus.Some DTI studies in patients with BD have found changes in the integrity of the white matter similar to those in patients with schizophrenia. When comparing the relatives of patients with schizophrenia with those with psychotic BD, they found a decrease in FA in a similar distribution of regions with respect to controls, but more pronounced in the relatives of patients with schizophrenia. In this last group, the area with the greatest differences compared to controls was the genu of the corpus callosum. A in relatives of patients with BD it was the upper region of the left posterior corona radiata. In the group of patients and relatives with BD, the differences were noticeable in young subjects, but were not found in older subjects. This may indicate that decreases in FA occur at early stages but do not progress later over the course of the disorder.<a class="elsevierStyleCrossRef" href="#bib0185">37</a>Of the first-degree relatives, the child and adolescent offspring of patients with BD (offspring of parent(s) with BD [OPBD]) are a vulnerable group, which may even have subsyndromal symptoms of mania and other early psychiatric disorders.<a class="elsevierStyleCrossRef" href="#bib0190">38</a> The presence of psychopathology in this population seems to be related to different findings than in the offspring of control parents (OCP).A study conducted in 20 asymptomatic OPBD found a decrease over time in FA values in the left corpus callosum and no change in FA in the right inferior longitudinal fasciculus, compared to the linear increase in FA in OCP in these two areas.<a class="elsevierStyleCrossRef" href="#bib0195">39</a> Another study,<a class="elsevierStyleCrossRef" href="#bib0200">40</a> which expanded its sample to individuals with a first-degree relative or two second-degree relatives, showed that healthy young people at risk of BD had lower FA in a wide group of regions, such as the corpus callosum, the internal and external capsule, the superior and inferior longitudinal, fronto-occipital and uncinate fasciculi, and the corticospinal tract.The findings of studies conducted in OPBD with psychiatric symptoms have been conflicting. A study conducted in 25 young OPBD with associated emotional dysregulation found that these patients had higher FA in the corpus callosum, the cingulum, and the superior and inferior longitudinal, superior fronto-occipital and uncinate fasciculi.<a class="elsevierStyleCrossRef" href="#bib0205">41</a> Frazier et al.<a class="elsevierStyleCrossRef" href="#bib0135">27</a> showed a decrease in FA in the superior longitudinal fasciculus both in paediatric OPBD with ADHD, behavioural disorders and anxiety disorders and in paediatric OPBD diagnosed with BD. However, the FA values were much lower in the second group, mainly in the cingulate and paracingulate gyri, which could indicate that these areas are more involved in the disease state rather than in the risk state. Lastly, a study<a class="elsevierStyleCrossRef" href="#bib0210">42</a> conducted on 108 young people aged 8−21 found a reduction in FA in the bilateral corticospinal tract and the corpus callosum in BD patients and first-degree relatives, compared to healthy subjects with no family history of BD. However, in the group of relatives, corticospinal tract alterations were greater in individuals diagnosed with ADHD, suggesting that this finding is not very specific for BD.Two studies in young relatives of patients with BD looked for an association between depressive episodes and imaging findings. In their longitudinal study, Ganzola et al.<a class="elsevierStyleCrossRef" href="#bib0215">43</a> found no differences in the subgroups of individuals at high risk between those who suffered from depression and those who did not. Roberts et al.<a class="elsevierStyleCrossRef" href="#bib0220">44</a> found that the subgroup of participants with a high familial risk of BD and recurrent depressive episodes had lower FA in the corpus callosum than those who did not have these episodes.Finally, a longitudinal study in young individuals with familial risk of BD versus a control group found that the trajectories of FA reduction were similar in both groups. However, they also detected reduced baseline FA in the subjects of interest versus the controls, which may indicate that alterations in structural connectivity do not arise close to the onset of the disease but much earlier, from birth or early childhood.<a class="elsevierStyleCrossRef" href="#bib0225">45</a>DiscussionThe available literature on changes in white matter integrity determined by DTI in child and adolescent relatives of patients with BD is limited, and there is little consensus from one study and another. However, most show that healthy young people with familial risk of BD do have differences compared to those without a genetic predisposition.Studies show that both BD patients and at-risk relatives have lower FA in specific brain regions. Most of these alterations are shared by both groups in the corpus callosum,<a class="elsevierStyleCrossRefs" href="#bib0120">24,33</a> the cingulum,<a class="elsevierStyleCrossRef" href="#bib0135">27</a> the superior<a class="elsevierStyleCrossRef" href="#bib0135">27</a> and inferior longitudinal fasciculi, and the fronto-occipital and uncinate fasciculi.<a class="elsevierStyleCrossRefs" href="#bib0165">33,39</a> However, some studies have shown that, compared to controls, FA is much lower in patients with BD and the FA of their relatives is at an intermediate point between the two groups.<a class="elsevierStyleCrossRefs" href="#bib0135">27,34</a> This could mean that the changes in FA are markers of vulnerability.Lower FA in regions such as the internal capsule,<a class="elsevierStyleCrossRef" href="#bib0125">25</a> the cingulate and paracingulate gyri,<a class="elsevierStyleCrossRef" href="#bib0200">40</a> the corona radiata<a class="elsevierStyleCrossRef" href="#bib0230">46</a> and the right orbitofrontal cortex<a class="elsevierStyleCrossRef" href="#bib0150">30</a> has only been described in studies of patients with BD and not in OPBD, which may suggest that these tracts have a more direct association with the disease state or the environmental factors which influence its development.There is heterogeneity among the populations studied, patients and relatives, which makes it difficult to interpret the findings and make conclusions about the changes in the structure of the white matter. Some studies include family members with personality disorders, ADHD or anxiety disorders, making it difficult to establish whether FA changes correspond to specific markers of vulnerability to BD or can be explained by other disorders. The administration of medications for BD may also generate changes in the white matter, as is known with lithium; it seems to affect axon integrity, which counteracts alterations in structural connectivity in these patients.<a class="elsevierStyleCrossRef" href="#bib0235">47</a> The different techniques in image processing may also have a hand in the inconsistency of the findings. Finally, the variety in the age of the relatives included in the studies makes it difficult to formulate hypotheses, as the DTI measurements change continuously from birth to late adulthood.<a class="elsevierStyleCrossRef" href="#bib0050">10</a>ConclusionsDespite the above limitations, the findings of reduced FA in different axonal tracts involved in emotional and cognitive functions in children and adolescents with familial risk of BD may be a good starting point for a better understanding of the pathophysiological bases and identifying new biomarkers of vulnerability to BD.FundingThis project was funded by Colciencias No. 111577757629: “Características clínicas, marcadores genéticos, y factores de adversidad psicosocial que predicen Trastorno por Déficit de atención con Hiperactividad (TDAH) en hermanos de alto riesgo” [Clinical characteristics, genetic markers, and psychosocial adversity factors that predict attention deficit hyperactivity disorder (ADHD) in high-risk siblings]; and also by CODI2017-16250: “Factores de adversidad psicosocial, genética y clínica asociada al TDAH en hermanos en alto riesgo” [Factors of psychosocial, genetic and clinical adversity associated with ADHD in siblings at high risk].

Diffusion tensor imaging (DTI) studies have enabled these changes to be elucidated with higher quality. Due to BD’s high heritability, some studies have been conducted in relatives of BD patients looking at white matter integrity, and have found that structural connectivity may also be affected. This alteration has been proposed as a potential BD biomarker of vulnerability. However, there are few studies in children and adolescents. ObjectiveTo conduct a review of the literature on changes in white matter integrity determined by DTI in high-risk children and adolescents. ResultsBrain structural connectivity in the paediatric population is described in studies using DTI. Changes in the myelination process from its evolution within normal neurodevelopment to the findings in fractional anisotropy (FA) in BD patients and their high-risk relatives are also described. ConclusionsStudies show that both BD patients and their at-risk relatives present a decrease in FA in specific brain regions.
