As the leading association in the field of neurology, the EAN is always striving to do pioneering work by developing new approaches for the meeting and exchange of scientific knowledge. The theme of the anniversary year was “Happiness”. Positive news and inspiring experts pointed the way to the future of neurology. <\/strong><\/p>\n\n\n\n\n\n\n\n

Middle-aged and older adults who have frequent disturbing dreams may be more at risk of cognitive decline and dementia.\nResearchers from Imperial College London (United Kingdom) investigated the association between the frequency of self-reported distressing dreams and the risk of cognitive decline and dementia in men and women in the general population [1].\nThe team assessed the frequency of distressing dreams using data collected in middle-aged adults from the Midlife in the United States (MIDUS) study and in 2600 older adults from the Osteoporotic Fractures in Men Study <\/em>(MrOS) and the Study of Osteoporotic Fractures<\/em> (SOF).\nCompared to middle-aged adults who reported having no disturbing dreams at baseline, those who reported having weekly disturbing dreams had a fourfold risk of experiencing cognitive decline.\nIn older adults, the difference in dementia risk was 2.2 times higher. <\/p>\n\n\n\n

While stress, anxiety or depression can cause disturbing dreams, other factors such as scary content in movies or a person’s genes can also trigger disturbing dreams.\nRecent research has shown that some people have a set of genes that make them prone to nightmares.\nOther studies show that people whose parents have nightmares are more likely to have them.\nThe link between nightmares and brain diseases such as Parkinson’s disease has already been established in the literature, but could also help predict autoimmune diseases such as lupus and attention deficit hyperactivity disorder (ADHD) in childhood.\nThese correlations should therefore be investigated in detail.\nIf the cause is psychological, appropriate treatment should be sought to better manage the stress levels, either through lifestyle changes, psychotherapy or medication.\nIn the case of nightmares that have no obvious cause and impair quality of life, image therapy shortly before bedtime can be helpful. <\/p>\n\n\n\n

Parental smoking increases the risk of MS<\/h3>\n\n\n\n

A study shows that selective exposure to parental smoking at a young age can increase the risk of MS in the general population in different ways [2].\nUsing data collected as part of the Environmental Risk Factors In Multiple Sclerosis (EnvIMS) study, a large multinational population-based case-control study, researchers examined the association between MS and smoking habits, maternal smoking during pregnancy and maternal or paternal smoking in the Canadian, Italian and Norwegian populations.\nIn Norwegians, an association was found between MS and maternal smoking during pregnancy and maternal smoking.\nIn Canadians, a tendency towards an association between paternal smoking and MS was found, while in the Italian population no significant association with parental smoking was found. <\/p>\n\n\n\n

Selective exposure to parental smoking at a young age may increase the risk of MS in the general population and regardless of the subjects’ past or current smoking habits.\nHowever, the lack of an association between MS and parental smoking history in some populations may be due to the smaller effect on MS risk compared to other factors.\nThere are a variety of genetic and environmental risk factors that interact in MS.\nThe timing of exposure to environmental factors, e.g. breastfeeding or infections such as mononucleosis, is also important.\nIn the early years of life, infection can be protective, but later in life it can be a risk factor. <\/p>\n\n\n\n

While active smoking is a known risk factor for the development of MS and a poor prognosis, the effect of previous exposure to parental smoking, including maternal smoking during pregnancy, had not yet been well defined.\nWhen you compare two studies recently published on maternal smoking during pregnancy, they say the opposite.\nOne says there is no link, while the other concludes that children of mothers who smoked had a higher risk of developing MS.\nThis is confusing.\nResearch needs to distinguish between maternal smoking in the prenatal period and parental smoking, i.e. passive smoking in childhood.\nAnother factor that needs to be taken into account is that if your parents smoke, you are more likely to become a smoker, which in turn affects your risk of developing MS.\nSo there are a lot of confounding factors in this type of study if you don’t adjust the results.\nFuture research should further investigate not only MS risk factors but also patient prognosis. <\/p>\n\n\n\n

Individual therapy management of myasthenia gravis<\/h3>\n\n\n\n

Myasthenia gravis (MG) is diagnosed by history and examination, autoantibody tests and electrophysiological tests [3].\nMG is caused by autoantibodies that bind to the postsynaptic membrane at the neuromuscular junction.\nIgG antibodies against acetylcholine receptor (AChR), MuSK or LRP4 affect AChRs through receptor cross-linking, complement activation, AChR blockade or impaired AChR clustering.\nThe IgG subclass varies.\nBoth thymic hyperplasia and thymoma can induce the production of AChR autoantibodies and MG.\nIn MG, active synthesis of new AChRs occurs and the structural postsynaptic changes are reversible.\nMG treatment should be in accordance with international guidelines and at the same time adapted to the individual patient.\nTreatment decisions should be made jointly by the neurologist and the patient.\nTreatment should be based on the autoantibody status, generalization and severity of MG and thymic pathology.\nSymptomatic drug therapy with acetylcholine esterase inhibitors is a primary therapy.\nImmunotherapy should be offered to all patients who have not achieved their treatment goals.\nThe combination of prednisolone and azathioprine is the first choice for immunotherapy.\nRituximab is an alternative, especially for MuSK-MG and new-onset AChR-MG.\nMycophenolate, tacrolimus and methotrexate are other commonly used immunosuppressants.\nThymectomy should be performed for thymoma and generalized MG with AChR antibodies if the patient is under 50 years of age.\nComplement inhibitors and FcRn blockers have a proven and clinically useful effect in most MG patients.\nThey improve symptoms after just one to two weeks.\nDue to the very high drug costs, their use is limited to difficult-to-treat and severe MG and depends on local availability, formal approval and reimbursement policies.\nIn refractory cases, new and experimental therapies may be considered.\nPhysical activity is safe and beneficial in MG.\nAt least 150 minutes per week is recommended.\nSuccessful MG treatment depends on the timely combination of measures. <\/p>\n\n\n\n

Real-world data at nOH<\/h3>\n\n\n\n

The treatment of neurogenic orthostatic hypotension (nOH) is based on consensus-based approaches.\nThere is a lack of real-world data on long-term efficacy and safety.\nNow the response to antihypotonics has been investigated in a longitudinal cohort of patients with synuclein-induced nOH (PAF, PD, DLB and MSA) [4].\nThe severity of cardiovascular autonomic insufficiency was determined by autonomic function tests.\nResponse to medication was measured with a semi-composite questionnaire that assessed the number of falls\/month and hospitalizations\/trimester, orthostatic symptom burden, quality of life and blood pressure monitoring.\n101 patients completed the questionnaire.\n61 patients were in long-term treatment (26 with one, 35 with several antihypertensive drugs), 40 in non-pharmacological treatment due to early disease stage, severe supine hypertension, immobilization or insensitivity to medication.\nThe number of falls and hospitalizations was 2 and 0.3, respectively.\nThe composite OHQ score (range 1-10) was 7.24.\nThe composite SF36 scores for physical and mental complaints (range: 0-100) were 33.2 and 38.9, respectively.\nThe level of nOH was 56\/27 mmHg in treated patients compared to 29\/6 mmHg in untreated patients.\nDespite multiple antihypertensive use, two-thirds of patients with nOH were significantly symptomatic, as confirmed by fall rates and hospitalizations.\nThese results emphasize the critical nature of nOH, the current gaps in pharmacological treatment and the profound impact on patients’ daily functioning. <\/p>\n\n\n\n

Subtypes in Parkinson’s disease<\/h3>\n\n\n\n

In Parkinson’s disease (PD), sleep is often impaired, with pain being one of the possible causes.\nThis can lead to difficulties in initiating and maintaining sleep, one of the consequences being sleep fragmentation.\nTherefore, the relationship between pain and sleep disturbance in patients with Parkinson’s disease was investigated in more detail [5].\n131 Parkinson’s patients were included in this case-control study.\nThe pain domains (according to the King’s Parkinson’s Disease Pain Scale, K<\/em> PPS) were analyzed according to the presence of sleep disturbances.\nBased on a Pittsburgh Sleep Quality Index (PSQI) of >5, PD patients were categorized as “poor sleepers”, while patients with a score \u22645 were considered “good sleepers”.\n25.19% of patients fell into the “good sleeper” category and 74.8% into the “poor sleeper” category.\nPatients in the “poor sleeper” category had more severe pain in all areas of the KPPS scale than patients in the “good sleeper” category, with statistically significant results for the following areas: Musculoskeletal pain, chronic pain, chronic pain or central pain, nocturnal pain or pain associated with akinesia, and radicular pain.\nThe majority of the patients examined had a reduced quality of sleep.\nTheir pain is more prominent than that of people with uninterrupted sleep.\nA focus on treatment <\/p>\n\n\n\n

Survival with amyotrophic lateral sclerosis<\/h3>\n\n\n\n

The role of upper motor neuron (UMN) and lower motor neuron (LMN) involvement in amyotrophic lateral sclerosis (ALS) has been extensively studied in relation to clinical phenotype and survival.\nConversely, it is not known whether the rate of change in UMN (\u0394UMN) and LMN (\u0394LMN) signs provides useful information about the evolution of ALS.\nA retrospective inpatient cohort of 1000 ALS patients has now been analyzed in this regard [5].\nThe burden of UMN and LMN signs was assessed using the Penn Upper Motor Neuron Score and Lower Motor Neuron Score, respectively.\nThe time interval between symptom onset and first assessment was used to quantify \u0394UMN and \u0394LMN values.\nSurvival, time from symptom onset to percutaneous endoscopic gastrostomy (PEG) and to non-invasive ventilation (NIV), were used as outcome measures.\nThe ENCALS survival model was calculated for a subgroup of patients. <\/p>\n\n\n\n

The \u0394UMN and \u0394LMN values were found to be negatively associated with survival (\u0394UMN: HR = 1.30; \u0394LMN: HR = 4.22), time to PEG (\u0394UMN: HR = 1.34; \u0394LMN: HR = 4.46) and time to NIV (\u0394UMN: HR = 1.23; \u0394LMN: HR = 5.0).\nA cut-off value of 0.195 for \u0394LMN was determined to predict patients with expected short or longer survival.\nENCALS groups characterized by shorter survival were significantly associated with higher \u0394UMN and \u0394LMN values compared to those with longer survival. <\/p>\n\n\n\n

The results suggest that \u0394UMN and \u0394LMN may represent reliable clinical indices for estimating disease progression and survival of ALS patients.\nIndeed, these two measures provide distinct clinical information in addition to the information derived from the total burden of UMN and LMN signs at initial assessment. <\/p>\n\n\n\n
