Parkinson disease, late-onset

Parkinsonism refers to all clinical states characterized by tremor, muscle rigidity, slowed movement (bradykinesia) and often postural instability. Parkinson disease is the primary and most common form of parkinsonism. Psychiatric manifestations, which include depression and visual hallucinations, are common but not uniformly present. Dementia eventually occurs in at least 20% of cases. The most common sporadic form of Parkinson disease manifests around age 60; however, young-onset and even juvenile presentations are seen. [from GeneReviews]

Movement disorder

Imagine if parts of your body moved when you didn't want them to. If you have a movement disorder, you experience these kinds of impaired movement. Dyskinesia is abnormal uncontrolled movement and is a common symptom of many movement disorders. Tremors are a type of dyskinesia. . Nerve diseases cause many movement disorders, such as Parkinson's disease. Other causes include injuries, autoimmune diseases, infections and certain medicines. Many movement disorders are inherited, which means they run in families. Treatment varies by disorder. Medicine can cure some disorders. Others get better when an underlying disease is treated. Often, however, there is no cure. In that case, the goal of treatment is to improve symptoms and relieve pain.  [from MedlinePlus]

Persistent hyperinsulinemic hypoglycemia of infancy

Familial hyperinsulinism (referred to as FHI in this GeneReview) is characterized by hypoglycemia that ranges from severe neonatal-onset, difficult-to-manage disease to childhood-onset disease with mild symptoms and difficult-to-diagnose hypoglycemia. Neonatal-onset disease manifests within hours to two days after birth. Childhood-onset disease manifests during the first months or years of life. In the newborn period, presenting symptoms may be nonspecific, including seizures, hypotonia, poor feeding, and apnea. In severe cases, serum glucose concentrations are typically extremely low and thus easily recognized, whereas in milder cases, variable and mild hypoglycemia may make the diagnosis more difficult. Even within the same family, disease manifestations can range from mild to severe. Individuals with autosomal recessive familial hyperinsulinism, caused by pathogenic variants in either ABCC8 or KCNJ11 (FHI-KATP), tend to be large for gestational age and usually present with severe refractory hypoglycemia in the first 48 hours of life; affected infants usually respond only partially to diet or medical management (i.e., diazoxide therapy) and thus may require pancreatic resection. Individuals with autosomal dominant FHI-KATP tend to be appropriate for gestational age at birth, to present at approximately age one year (range: 2 days - 30 years), and to respond to diet and diazoxide therapy. Exceptions to both of these generalities have been reported. FHI-GCK, caused by pathogenic variants in GCK, may be much milder than FHI-KATP; however, some persons have severe, diazoxide-unresponsive hypoglycemia. FHI-HADH, caused by pathogenic variants in HADH, tends to be relatively mild, although severe cases have been reported. Individuals with FHI-HNF4A, caused by pathogenic variants in HNF4A, are typically born large for gestational age and have mild features that respond to diazoxide treatment. FHI-UCP2, caused by pathgoenic variants in UCP2, is a rare cause of diazoxide-responsive FH1. Hyperammonemia/hyperinsulinism (HA/HI) is associated with mild-to-moderate hyperammonemia and with relatively mild, late-onset hypoglycemia; most but not all affected individuals have pathogenic variants in GLUD1. [from GeneReviews]
