A 2014 review found that "even in a theoretical case of binge drinking, the children would not be subjected to clinically relevant amounts of alcohol [through breastmilk]", and would have no adverse effects on children as long as drinking is "occasional".If the mother consumes too much caffeine, it can cause irritability, sleeplessness, nervousness and increased feeding in the breastfed infant. Moderate use (one to two cups per day of coffee, tea, or cola) usually produces no effect. Breastfeeding mothers are advised to restrict or avoid caffeine if her baby reacts negatively to it. Cigarette smoking is thought to increase the effects of caffeine in the baby. Cannabis
Cannabis is listed by the American Association of Pediatrics as a compound that transfers into human breast milk. Research demonstrated that certain compounds in marijuana have a very long half-life. Diet
An exclusively breastfed baby depends on breast milk completely so it is important for the mother to maintain a healthy lifestyle, and especially a good diet. Consumption of 1500–1800 calories per day could coincide with a weight loss of 450 grams (one pound) per week. While mothers in famine conditions can produce milk with highly nutritional content, a malnourished mother may produce milk with decreased levels of several micronutrients such as iron, zinc, and vitamin B12. She may also have a lower supply than well-fed mothers. There are no foods that are absolutely contraindicated during breastfeeding, but a baby may show sensitivity to particular foods that the mother eats.
Catatonia presents as a motor disturbance in which patients will display marked reduction in movement, marked agitation, or a mixture of both despite having the physical capacity to move normally. These patients may be unable to start an action or stop one. Movements and mannerisms may be repetitive, or purposeless.The most common signs of catatonia are immobility, mutism, withdrawal and refusal to eat, staring, negativism, posturing (rigidity), rigidity, waxy flexibility/catalepsy, stereotypy (purposeless, repetitive movements), echolalia or echopraxia, verbigeration (repeat meaningless phrases). It should not be assumed that patients presenting with catatonia are unaware of their surroundings as some patients can recall in detail their catatonic state and their actions.There are several subtypes of catatonia and they are characterized by the specific movement disturbance and associated features. Although catatonia can be divided into various subtypes, the natural history of catatonia is often fluctuant and different states can exist within the same individual. Subtypes
Withdrawn Catatonia: This form of catatonia is characterized by decreased response to external stimuli, immobility or inhibited movement, mutism, staring, posturing, and negativism. Patients may sit or stand in the same position for hours, may hold odd positions, and may resist movement of their extremities.Excited Catatonia: Excited catatonia is characterized by odd mannerisms/gestures, performing purposeless or inappropriate actions, excessive motor activity restlessness, stereotypy, impulsivity, agitation, combativeness. Speech and actions may be repetitive or mimic another persons. People in this state are extremely hyperactive and may have delusions and hallucinations. Catatonic excitement is commonly cited as one of the most dangerous mental states in psychiatry.
